See ICFS File No. SAT-LOA-2019102-00001 (grant in part Dec. 10, 2019). 1 This application, as amended, was previously granted-in-part, and deferred-in-part. See ICFS File Nos. SAT-MOD- 20220906-00099, SAT-AMD-20221014-00136, granted-in-part March 3, 2013, reissued March 13, 2023 (March 2023 Grant Stamp). In that prior grant, we deferred action on the portions of HE360’s application for license modification for deployments beyond “Cluster 7”. We defer action at this time regarding modification to the license for satellites deployed in Clusters 10 and after. This grant is also without prejudice to any action taken in connection with HE360’s pending further modification request in ICFS File No. SAT-MOD-20230724-00181. On January 17, 2023, Space Exploration Technologies Corp. (SpaceX) filed an ex parte letter. Letter from David Goldman, Director of Satellite Policy, SpaceX, to Marlene H. Dortch, Secretary, FCC at 1 (dated Jan. 17, 2023). These issues are fully addressed in the accompanying Order. 2 See March 2023 Grant Stamp (modification of license to specify, for three satellites identified as Cluster 7: (1) additional antennas capable of receiving signals in certain UHF frequencies (250-350 MHz); (2) a change in the authorized satellite operational altitude range from 500-615 km to 475-615 km; and (3) changes in operations due to modification of the satellite propulsion system). 3 HE360’s Constellation was preceded by an experimental earth exploration three-satellite cluster called Pathfinder, which was separately coordinated with federal operators. See ELS File No. 0024-EX-CN-2017, as modified 0055-EX-CM-2019. The Pathfinder satellites successfully launched on December 3, 2018 and operational in the 2240 MHz, 2246 MHz, 2256 MHz (space-to-Earth), 432-438 MHz (Earth-to-space), 2410 MHz (space-to-space), and 8050 MHz, 8175 MHz, and 8300 MHz (space-to-Earth) frequency bands. Authorization for continued operations of this first cluster of three Pathfinder satellites under Part 25 of the Commission’s rules was included in the prior grant dated December 10, 2019. See ICFS File No. SAT-LOA-20190102-00001 (granted-in-part Dec. 10, 2019). Page 1 of 13 ATTACHMENT TO GRANT HawkEye 360, Inc. ICFS File Nos.

Further, HE360 commits to operating those terminals subject to such limitations. See ICFS File Nos. SAT-MOD-20220906-00099 and SAT-AMD-20200728- 00090, Letter from Tony Lin, Counsel for Hawkeye360, Inc. to Marlene H. Dortch, Secretary, FCC (Jan. 13, 2023). Page 5 of 13 ATTACHMENT TO GRANT HawkEye 360, Inc. ICFS File Nos. SAT-MOD-20220906-00099, SAT-AMD-20221014-00136 Unless otherwise specified herein, operations under this grant must comport with the legal and technical specifications set forth by the applicant or petitioner and with the Federal Communications Commission’s rules not waived herein. This grant is also subject to the following conditions:11 1. HE360 must prepare the necessary information, as may be required, for submission to the International Telecommunication Union (ITU) to initiate and complete the advance publication, coordination, due diligence, and notification process for these space stations, in accordance with the ITU Radio Regulations. HE360 will be held responsible for all cost-recovery fees associated with ITU filings. No protection from interference caused by radio stations authorized by other administrations is guaranteed unless coordination and notification procedures are timely completed or, with respect to individual administrations, by successfully completing coordination agreements. Any radio station authorization for which coordination has not been completed may be subject to additional terms and conditions as required to effect coordination of the frequency assignments of other administrations. See 47 CFR § 25.111(b). 2. Upon receipt of a conjunction warning from the 18th Space Control Squadron or other source, HE360 must review and take all possible steps to assess the collision risk, and mitigate collision risk if necessary. As appropriate, steps to assess and mitigate should include, but are not limited to: contacting the operator of any active spacecraft involved in such warning; sharing ephemeris data and other appropriate operational information with any such operator; modifying spacecraft attitude and/or operations. 3. The number of simultaneously operational satellites must not exceed 60. This number does not include the three Pathfinder satellites launched on December 3, 2018, under grants of experimental authorizations pursuant to Part 5 of the Commission’s rules.12 These three Pathfinder satellites must operate under this Part 25 authorization pursuant to the terms and parameters, including earth station power level agreements and mitigation activities, coordinated with Federal users as part of those grants of experimental licenses.13 4. For S-band command uplink operations in the 2025-2110 MHz band, HE360 earth stations must operate a duty cycle of no more than 10% to ensure that the constellation complies with interference criteria contained in Recommendation ITU-R SA. 1155-2.14 5. This grant includes authority to deploy and operate technically identical replacement satellites during the term of the license, pursuant to 47 CFR § 25.113(i). Based on information provided by the applicant, the anticipated total number of satellites to be deployed during the license term would be 174. Deployment involving a different satellite bus will require the filing and approval of a license modification request in order to, inter alia, address any differences in debris risks due to changes in the physical characteristics of the spacecraft.15 6. HE360 must comply with any new rules adopted by the Commission as a result of the rulemaking in IB Docket No. 18-313.16 11 With respect to those frequency bands shared with Federal spectrum users, Federal operators have indicated that Federal missions brought into use after issuance of this grant may prevent future modification or renewal. 12 See supra note 4. We note that the total number of simultaneously operational satellites refers specifically to those satellites operating in frequencies other than TT&C frequencies and does not include non-operational satellites that continue to operate in TT&C frequency bands as part of approved post-mission disposal plans. 13 See, e.g., ELS File No. 0024-EX-CN-2017, as modified 0055-EX-CM-2019. 14 As noted supra, starting with HE360 satellites in Cluster 9, HE360 plans to remove the S-band transmitter used to provide emergency backup, telemetry (2200-2290 MHz). 15 Deployment of satellites with different propulsion system characteristics, will require grant of a license modification. 16 See Mitigation of Orbital Debris in the New Space Age, Notice of Proposed Rulemaking, FCC 18-159, 33 FCC Rcd 11352 (2018); Mitigation of Orbital Debris in the New Space Age, Report and Order and Further Notice of Proposed Rulemaking, FCC 20-54, 35 FCC Rcd 4156 (2020).

HE360’s space-to-Earth and Earth-to-space operations shall be strictly limited to durations when the HE360 space stations referenced within this license request are visible to the corresponding earth station locations listed in Appendix A of the attachment to this grant, noting the additional restrictions within this grant. 8. We grant, on our own motion, a waiver of the U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), to allow non-conforming use of the 2200-2290 MHz band for HE360 to conduct telemetry and tracking,, subject to the condition that HE360 operates on a non-interference basis, accepts any interference from authorized services in these bands, and complies with the other conditions below regarding operations in these bands. HE360 intends to operate TT&C in these frequencies but will not operate in the EESS using this frequency band. The 2200-2290 MHz band is allocated to the space operation (space-to-Earth) and space research (space-to-Earth) services in the U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), for federal use only.17 In this instance we find good cause to waive the Table of Allocations to allow HE360 to operate command links only with its satellites based on HE360’s coordination with federal users in the frequency band. Additionally, HE360 shall be aware that non-Federal space-to-Earth transmissions in the 2200-2290 MHz are not permitted to earth stations within the US&P. Based on HE360’s coordination with federal users in the frequency band, which should ensure that any authorized federal users are protected from harmful interference, we find good cause to waive the U.S. Table of Frequency Allocations to allow HE360 to operate telemetry and tracking with its satellites in the 2200- 2290 MHz band. 9. On our own motion, we grant a waiver of the U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), for HE360 to conduct non-Federal space-to-space EESS operations at 2410 MHz with the first HE360 satellite cluster launched on December 3, 2018 only, subject to the condition that operations in this band do not cause harmful interference and that HE360 may not claim protection from interference. The 2400-2417 MHz band, inter alia, is allocated to the amateur service on a primary basis in the U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), for non-Federal use. 10. On our own motion, we grant a waiver of the U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), for HE360 to conduct non-Federal Earth-to-space operations in the 432-438 MHz band, with the first HE360 satellite cluster launched on December 3, 2018 only, subject to the condition that operations in this band do not cause harmful interference and that HE360 may not claim protection from interference. The 432-438 MHz band is allocated to the Earth exploration-satellite service (active) on a secondary basis in the U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), (c)(397), for Federal use only. 11. Power flux-density from HE360’s operations in the 8025-8400 MHz band must not exceed the limits in No. 22.5 and Table 21-4 of the International Telecommunication Union’s Radio Regulations. In addition, power spectral density levels at space research service earth stations from space-to-Earth operations in the 8025-8400 MHz band must not exceed the limits/protection criteria in Recommendation ITU-R SA.1157-1, and the guidelines for systems operating in the 8025-8400 MHz band in Recommendation ITU-R SA.1810 must be followed. 12. Operations pursuant to this license must not cause harmful interference to stations operating in the 2025- 2110 MHz band in accordance with the United States Table of Frequency Allocations. See 47 CFR § 2.106(a), (c)(347). 13. Transmissions in the 2025-2110 MHz, 8025-8400 MHz, and 2200-2290 MHz bands18 may only be made to/from earth stations coordinated with federal agencies, including National Aeronautics and Space Administration (NASA), Department of Commerce/National Oceanic and Atmospheric Administration (DOC/NOAA), and the United States Air Force Spectrum Management Office (AFSMO). Any use of Federal ground stations shall be coordinated by HE360’s federal government customers with AFSMO (jimmy.nguyen@us.af.mil), NASA (HQ-SatCoord@mail.nasa.gov) and DOC/NOAA (edna.prado@noaa.gov). A list of coordinated non-Federal earth stations is attached as Appendix A. HE360 shall provide the FCC with an updated list of coordinated non-Federal earth stations within ten business days following any changes to that list.19 Page 7 of 13 ATTACHMENT TO GRANT HawkEye 360, Inc. ICFS File Nos. SAT-MOD-20220906-00099, SAT-AMD-20221014-00136 14. Earth-to-space transmissions in the 2025-2110 MHz band to HE360 satellites must be coordinated with the SBE (Society of Broadcast Engineers). 15. Transmissions in the 2025-2110 MHz, 2200-2290 MHz, and 8025-8400 MHz bands are limited to the center frequencies and emission bandwidths coordinated with Federal users set forth in the Frequencies section of this grant. 16. In the 2025-2110 MHz band, HE360 shall comply with the following limitations: a. The primary uplink (Earth-to-space) emission bandwidths shall be limited to 170 kHz, 1.33 MHz, and 2.66 MHz. All uplink (Earth-to-space) 2.66 MHz emission bandwidth transmissions shall be limited to a duty cycle of no more than 10% per earth station per satellite. b. All uplink (Earth-to-space) transmissions to HE360 satellites using a center frequency of 2046.5 MHz and emission bandwidth of 1.33 MHz from any earth station located in the Northern hemisphere at latitudes greater than 60 degrees or in the Southern hemisphere at latitudes below 50 degrees (e.g. above 60N or below 50S) shall cease transmissions when the NASA PUNCH satellites (4 total) are within view of the respective earth station. c. All uplink (Earth-to-space) transmissions using center frequencies of 2064.965 MHz and 2065.965 MHz shall be limited to a duty cycle of less than 4% per earth station per satellite. d. All uplink (Earth-to-space) transmissions using center frequencies of 2053.0 MHz, 2053.7 MHz, 2077.4 MHz, and 2075.0 MHz shall cease transmissions during the Artemis-IV and later Artemis missions from launch to launch + 48 hours. 17. Power flux-density levels at the surface of the Earth resulting from space-to-Earth operation in the 2200- 2290 MHz band must not exceed the limits in Table 21-4 of the ITU Radio Regulations, and the power spectral density levels at space research service earth stations resulting from space-to-Earth operations in the 2200-2290 MHz band must not exceed the protection criteria in Recommendation ITU-R SA.1157-1 and Recommendation ITU-R SA.609-2. 18. All downlink (space-to-Earth) operations in the 2200-2290 MHz band shall be restricted to communication with earth stations identified in Appendix A that are located outside the US&P.20 19. In the event a spacecraft emergency requires activation of the emergency backup downlink (space-to- Earth) capability using center frequencies of 2242.0 MHz, 2254.0 MHz, or 2260.0 MHz, HE360 shall immediately notify the NASA JSC Spectrum Management (jsc-dl-spectrum-management@mail.nasa.gov) and Travis Inghram (HQ-SatCoord@mail.nasa.gov). Emergency backup downlink operations in the 2200-2290 MHz band shall be limited to spacecraft emergency situations only, and all other usage is not authorized. 20. All reception must comport with the requirements on unauthorized publication or use of communications in section 705 of the Communications Act of 1934, as amended (47 U.S.C. § 605). This license grant does not constitute an "authorization" with respect to the activities specified in section 705 of the Communications Act or in related provisions of chapter 119, Title 18, United States Code. 17 Although there are additional footnote allocations for non-Federal space research, space operations, and EESS, these non- federal allocations are limited to circumstances not relevant to HE360’s operations. See 47 CFR § 2.106(a)(c)(96) and (c)(303). 18 As noted supra, starting with HE360 satellites in Cluster 9, HE360 plans to remove the S-band transmitter used to provide emergency backup, telemetry downlinks (2200-2290 MHz). 19 A list of earth stations already coordinated with federal agencies is attached as Appendix A to this grant. 20 See also condition 8.

The U.S. Table of Frequency Allocations, Section 2.106(a), is waived with respect to reception of ADS-B signals in the 1087.7-1092.3 MHz frequency band, for satellites through Cluster 8. This band was allocated internationally for the aeronautical mobile-satellite (R) service (AMS(R)S) (Earth-to-space) on a primary basis, at WRC-15, and is limited to the space station reception of ADS-B emissions from aircraft transmitters that operate in accordance with recognized international aeronautical standards. Stations operating in the AMS(R)S shall not claim protection from stations operating in the aeronautical radionavigation service. Resolution 425 (WRC-15) shall apply.21 Any future protection of ADS-B reception will be governed by the relevant status in the Table of Frequency Allocations and must be in accordance with any subsequent rulemaking proceedings to implement any new domestic allocations or service rules. 22. The U.S. Table of Frequency Allocations, Section 2.106(a), is waived with respect to reception of AIS signals in the 156.7625-156.7875 MHz (AIS 3), 156.8125-156.8375 MHz (AIS 4), 161.9625-161.9875 MHz (AIS 1) and 162.0125-162.0375 MHz (AIS 2).22 As a condition of this waiver, HE360 must not claim protection for reception of messages in the 156.0125-162.0375 MHz frequency band that is not in accordance with the Table of Frequency Allocations for the pertinent area and may only claim protection to the extent provided by the status of the reception under the Table of Frequency Allocations. 23. HE360 may claim protection for reception in the 156.7625-162.0375 MHz band only to the extent permitted under the U.S. Table of Frequency Allocations for domestic operations or the ITU Radio Regulations for international operations, as of the time of operation. Operations in the 156.7625-162.0375 MHz band must be in accordance with any Commission rulemakings subsequent to the release of this license that implement any new domestic allocations or service rules for these bands.23 24. The U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), is waived with respect to reception of the DSC signal in the 156.5125-156.5375 MHz frequency band on a non-conforming, non-harmful interference basis. The 156.5125-156.5375 MHz frequency band is allocated to Maritime Mobile on a primary basis for non-Federal operations and in all ITU Regions.24 In the United States, there is also limited use of this band by certain grandfathered public safety radio pool licensees.25 As a condition of this waiver, HE360 must not claim protection for reception of messages in the 156.5125-156.5375 MHz frequency band that is not in accordance with the Table of Frequency Allocations for the pertinent area and may only claim protection to the extent provided by the status of the reception under the Table of Frequency Allocations. 25. The U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), is waived with respect to reception of EPIRB signals in the 406-406.1 MHz frequency band. The 406-406.1 MHz frequency band is allocated for Mobile-Satellite Service (MSS) and is limited to low-power satellite emergency position-indicating radio beacons 21 We previously found good cause to waive sections 2.102(a) and 2.106 to permit reception of ADS-B messages on an unprotected basis in the United States because doing so will not cause any interference or unreasonably preclude other services, and make the same finding with respect to Cluster 8. 22 We previously found that the reception of AIS transmissions cannot cause harmful interference, and these transmissions will be present pursuant to existing authorizations using frequencies allocated to other services regardless of whether they are received by a HE360 satellite. We also concluded that the service HE360 proposes will serve the public interest by providing critical near real-time maritime data of interest for both government and commercial users. We make the same findings with respect to Clusters 8 and 9. 23 Iridium Order and Authorization, 31 FCC Rcd at 8689, para. 50. 24 47 CFR § 2.106(a), (b)(111), (266), and (c)(52). 25 47 CFR § 2.106(a), (c)(266). We found that the reception of DSC transmissions cannot cause harmful interference, and these transmissions will be present pursuant to existing authorizations using frequencies allocated to other services regardless of whether they are received by a HE360 satellite. We also concluded that the service HE360 proposes will serve the public interest by providing near real-time maritime safety data. Exhibit A: Narrative at 44. We make the same findings with respect to Clusters 8 and 9. Page 9 of 13 ATTACHMENT TO GRANT HawkEye 360, Inc. ICFS File Nos. SAT-MOD-20220906-00099, SAT-AMD-20221014-00136 (EPIRB).26 As a condition of this waiver, HE360 must not claim protection for reception of messages in the 406- 406.1 MHz frequency band that is not in accordance with the Table of Frequency Allocations for the pertinent area and may only claim protection to the extent provided by the status of the reception under the Table of Frequency Allocations. 26. The U.S. Table of Frequency Allocations, § 2.106(a), is waived, to the extent necessary, with respect to reception of signals transmitted from terrestrial sources (Earth-to-space) in frequency bands used by the Global Positioning System (GPS). The frequency bands used by the GPS are allocated for Space-to-earth transmissions.27 27. HE360’s request for a waiver of the U.S. Table of Frequency Allocations, 47 CFR § 2.106(a),28 with respect to reception of inter-satellite signals from the Inmarsat satellite system in the 1525-1544 MHz and 1545- 1559 MHz frequency bands is GRANTED, on an unprotected, non-interference basis.29 Although the allocations in this frequency band do not include a directional indicator for space-to-space communications, reception by the HawkEye satellites of these frequencies will not in any way alter the interference environment, as the received signal will be indistinguishable in its technical characteristics from signals transmitted in the allocated space-to- Earth direction. 28. HE360’s request for a waiver of the Table of Frequency Allocations, 47 CFR § 2.106(a), to receive inter- satellite signals from the Inmarsat satellite system in the 1626.5-1645.5 and 1646.5-1660.5 MHz frequency bands on an unprotected, non-interference basis, is GRANTED.30 Additionally, we grant on our own motion waiver to of the Table of Frequency Allocations, 47 CFR § 2.106(a), to transmit inter-satellite signals to the Inmarsat satellite system in the 1626.5-1645.5 MHz and 1646.5-1660.5 MHz frequency bands on an unprotected, non- interference basis. The allocation for the Mobile-Satellite Service in which the Inmarsat system operates and that encompasses these bands does not include a space-to-space directional indicator. HE360 states that transmission on a non-conforming basis in the L-band frequencies will occur only on frequencies that Inmarsat assigns to the spaceborne Inmarsat BGAN terminals onboard the HE360 spacecraft. HE360 states that transmission on a non- conforming basis in the L-band frequencies will occur only on frequencies that Inmarsat assigns to the spaceborne Inmarsat BGAN terminals onboard the HE360 spacecraft. HE360 notes that these transmissions are approved and supported by Inmarsat and fall within its licensed spectrum.31 As with its other operations, Inmarsat will assign channels to the spacecraft consistent with its coordination agreements with other operators in the band, 26 47 CFR § 2.106(a), (b)(266). We found that the reception of EPIRB transmissions cannot cause harmful interference, and these transmissions will be present pursuant to existing authorizations using frequencies allocated to other services regardless of whether they are received by a HE360 satellite. We also concluded that the service HE360 proposes will serve the public interest by augmenting existing COSPAS-SARSAT architecture used to monitor and geolocate EPIRB distress signals. We make the same findings with respect to Clusters 8 and 9. The SARSAT (Search and Rescue Satellite Aided Tracking) system is operated by NOAA to detect and locate mariners, aviators, and recreational enthusiasts in distress. It uses NOAA satellites in low-earth and geostationary orbit to detect and locate distress signals and relay them from emergency beacons to a network of ground stations and the U.S. Mission Control Center, which processes the signals and alerts appropriate search and rescue authorities. SARSAT is part of the international COSPAS-SARSAT program. See http://www.sarsat.noaa.gov. 27 We found that the reception of transmitted signals from terrestrial sources (Earth-to-space) in frequency bands used by the Global Positioning System (GPS) cannot cause harmful interference to actual GPS (Space-to earth) operations. We make the same findings with respect to Clusters 8 and 9. 28 We note that waiver of 47 CFR § 25.112(a)(3) is unnecessary as this provision was removed from the Commission's rules effective Jan. 5, 2024. See Space Innovation; Expediting Initial Processing of Satellite and Earth Station Applications, Report and Order and Further Notice of Proposed Rulemaking, FCC 23-73 (Sept. 22, 2023) at para. 27; 88 Federal Register 84737 (Dec. 6, 2023). 29 See Legal Narrative at 8-9. 30 Legal Narrative at 8. 31 Id. at 9.

SAT-MOD-20220906-00099, SAT-AMD-20221014-00136 ensuring that there is no harmful interference between these systems.32 Inmarsat will maintain the same extent of positive control of HE360’s operations as it does for its other L-band users and will thereby be able to address any unlikely interference issues as required by Section 25.287 of the Commission’s Rules. 29. HE360 must maintain a U.S. point of contact available by telephone 24 hours per day, seven days per week, with the authority and ability to terminate operations authorized herein. The telephone number for this U.S. point of contact must also be provided to NTIA (ravery@ntia.doc.gov), DOC/NOAA (edna.prado@noaa.gov), and NASA (HQ-SatCoord@mail.nasa.gov). 30. HE360 shall provide the FCC and other federal agencies the initial orbital parameters (e.g. operating altitudes, inclination angle) for each cluster within 30 days following launch. Notification shall be provided to AFSMO (jimmy.nguyen@us.af.mil), NASA (HQ-SatCoord@mail.nasa.gov) and DOC/NOAA (edna.prado@noaa.gov). 31. Given the opportunity for additional entrants to operate in HE360’s requested frequency bands, this grant includes the previously-granted waiver to HE360 of the modified processing round requirements of 47 CFR §§ 25.156 and 25.175.33 32. Because HE360 must comply with the technical requirements in Part 2 of the Commission’s rules and the above-referenced power flux-density limits, which should prevent harmful interference to other operators in the band, this grant includes the previously-granted waiver of the default service rules in 47 CFR § 25.217(b).34 33. This license will become null and void if, at any time during the license term, there are no HE360 satellites operating. 34. In connection with the provision of service in any particular country, HE360 is obliged to comply with the applicable laws, regulations, rules, and licensing procedures of that country 35. HE360’s three Pathfinder satellites were successfully launched on December 3, 2018 and are operational. See ELS File No. 0024-EX-CN-2017. Authorization for continued operations of the three Pathfinder satellites under Part 25 of the Commission’s rules is included in this grant. We find that warehousing concerns are addressed in this situation through the imposition of condition 25 above. Thus, we decline to impose milestone and bond obligations on HE360. 36. HE360 must coordinate physical operations of spacecraft with any operator using similar orbits, for the purposes of eliminating collision risk and minimizing operational impacts. The orbital parameters specified in this grant are subject to change based on such coordination. 37. HE360 must provide a semi-annual report, by January 1 and July 1 each year, covering the preceding six month period, respectively, from June 1 to November 30 and December 1 to May 31. The report should include the following: Number of conjunction events identified for any HE360 system satellites during the reporting period, and the number of events that resulted in an action (maneuver or coordination with another operator), as well as any difficulties encountered in connection with the collision avoidance process and any measures taken to address those difficulties. HE360 must report any loss of control of HE360 satellites at altitudes above 350 km not less than 10 days following the loss of control. Based on the information reported, the license may be subject to additional terms and conditions, including additional reporting obligations, limitations on additional deployments, requirements for early removal of satellites from orbit, or any other appropriate conditions to limit collision risk. In the event of HE360 satellite 32 Id. 33 See DigitalGlobe, Inc., Order and Authorization, 20 FCC Rcd 15696 (Sat. Div., Int’l Bur. 2005) at para. 8. 34 Id., 20 FCC Rcd at 15702-03, para. 19.

SAT-MOD-20220906-00099, SAT-AMD-20221014-00136 failures resulting in more than 100 post-failure object years, HE360 may not deploy any additional HE360 satellites until the Commission has approved a license modification that includes an updated orbital debris mitigation plan addressing reduction in the failure rate or mitigation of the risk of satellite failures. 38. HE360 must communicate and collaborate with NASA to support safety of both HE360 and NASA assets and to preserve long-term sustainable space-based communications services. HE360 must report on the progress of its communications and collaboration efforts to the Commission in its regular reports specified in condition 27, above. HE360 must coordinate and collaborate with NASA to promote a mutually beneficial space environment that would minimize impacts to NASA’s science missions involving astronomy. 39. HE360 must coordinate with NSF to achieve a mutually acceptable agreement to mitigate the impact of its satellites (call sign S3165) on optical ground-based astronomy. HE360 must submit an annual report to the Commission, by January 1st each year covering the preceding year (1) describing whether it has reached a coordination agreement with NSF addressing optical astronomy; and (2) any steps HE360 has taken to reduce the impact of its satellites on optical astronomy. If HE360 provides a statement in the record that NSF has no concerns within 45 days following deployment of the HE360 satellites to approximately 590 km, no further reporting will be required. 40. The license term is 15 years, calculated from the deployment of the three Pathfinder satellites on December 3, 2018 (that is December 3, 2033). 41. Within 30 days after deployment of each satellite pursuant to this license, HE360 must file a notification with the Commission specifying its apogee and perigee altitudes and orbital inclination. Licensee/grantee is afforded thirty (30) days from the date of release of this action to decline the grant as conditioned. Failure to respond within this period will constitute formal acceptance of the grant as conditioned. This action is taken pursuant to Section 0.261 of the Commission’s rules on delegated authority, 47 CFR § 0.261, and is effective upon release. Station licenses are subject to the conditions specified in Section 309(h) of the Communications Act of 1934, as amended, 47 U.S.C. § 309(h).

In that prior grant, we deferred action on the portions of HE360’s application for license modification for deployments beyond “Cluster 7”. We defer action at this time regarding modification to the license for satellites deployed in Clusters 10 and after. This grant is also without prejudice to any action taken in connection with HE360’s pending further modification request in ICFS File No. SAT-MOD-20230724-00181. On January 17, 2023, Space Exploration Technologies Corp. (SpaceX) filed an ex parte letter. Letter from David Goldman, Director of Satellite Policy, SpaceX, to Marlene H. Dortch, Secretary, FCC at 1 (dated Jan. 17, 2023). These issues are fully addressed in the accompanying Order. 2 See March 2023 Grant Stamp (modification of license to specify, for three satellites identified as Cluster 7: (1) additional antennas capable of receiving signals in certain UHF frequencies (250-350 MHz); (2) a change in the authorized satellite operational altitude range from 500-615 km to 475-615 km; and (3) changes in operations due to modification of the satellite propulsion system). 3 HE360’s Constellation was preceded by an experimental earth exploration three-satellite cluster called Pathfinder, which was separately coordinated with federal operators. See ELS File No. 0024-EX-CN-2017, as modified 0055-EX-CM-2019. The Pathfinder satellites successfully launched on December 3, 2018 and operational in the 2240 MHz, 2246 MHz, 2256 MHz (space-to-Earth), 432-438 MHz (Earth-to-space), 2410 MHz (space-to-space), and 8050 MHz, 8175 MHz, and 8300 MHz (space-to-Earth) frequency bands. Authorization for continued operations of this first cluster of three Pathfinder satellites under Part 25 of the Commission’s rules was included in the prior grant dated December 10, 2019. See ICFS File No. SAT-LOA-20190102-00001 (granted-in-part Dec. 10, 2019). Page 1 of 13 ATTACHMENT TO GRANT HawkEye 360, Inc. ICFS File Nos.

SAT-MOD-20220906-00099 and SAT-AMD-20200728- 00090, Letter from Tony Lin, Counsel for Hawkeye360, Inc. to Marlene H. Dortch, Secretary, FCC (Jan. 13, 2023). Page 5 of 13 ATTACHMENT TO GRANT HawkEye 360, Inc. ICFS File Nos. SAT-MOD-20220906-00099, SAT-AMD-20221014-00136 Unless otherwise specified herein, operations under this grant must comport with the legal and technical specifications set forth by the applicant or petitioner and with the Federal Communications Commission’s rules not waived herein. This grant is also subject to the following conditions:11 1. HE360 must prepare the necessary information, as may be required, for submission to the International Telecommunication Union (ITU) to initiate and complete the advance publication, coordination, due diligence, and notification process for these space stations, in accordance with the ITU Radio Regulations. HE360 will be held responsible for all cost-recovery fees associated with ITU filings. No protection from interference caused by radio stations authorized by other administrations is guaranteed unless coordination and notification procedures are timely completed or, with respect to individual administrations, by successfully completing coordination agreements. Any radio station authorization for which coordination has not been completed may be subject to additional terms and conditions as required to effect coordination of the frequency assignments of other administrations. See 47 CFR § 25.111(b). 2. Upon receipt of a conjunction warning from the 18th Space Control Squadron or other source, HE360 must review and take all possible steps to assess the collision risk, and mitigate collision risk if necessary. As appropriate, steps to assess and mitigate should include, but are not limited to: contacting the operator of any active spacecraft involved in such warning; sharing ephemeris data and other appropriate operational information with any such operator; modifying spacecraft attitude and/or operations. 3. The number of simultaneously operational satellites must not exceed 60. This number does not include the three Pathfinder satellites launched on December 3, 2018, under grants of experimental authorizations pursuant to Part 5 of the Commission’s rules.12 These three Pathfinder satellites must operate under this Part 25 authorization pursuant to the terms and parameters, including earth station power level agreements and mitigation activities, coordinated with Federal users as part of those grants of experimental licenses.13 4. For S-band command uplink operations in the 2025-2110 MHz band, HE360 earth stations must operate a duty cycle of no more than 10% to ensure that the constellation complies with interference criteria contained in Recommendation ITU-R SA. 1155-2.14 5. This grant includes authority to deploy and operate technically identical replacement satellites during the term of the license, pursuant to 47 CFR § 25.113(i). Based on information provided by the applicant, the anticipated total number of satellites to be deployed during the license term would be 174. Deployment involving a different satellite bus will require the filing and approval of a license modification request in order to, inter alia, address any differences in debris risks due to changes in the physical characteristics of the spacecraft.15 6. HE360 must comply with any new rules adopted by the Commission as a result of the rulemaking in IB Docket No. 18-313.16 11 With respect to those frequency bands shared with Federal spectrum users, Federal operators have indicated that Federal missions brought into use after issuance of this grant may prevent future modification or renewal. 12 See supra note 4. We note that the total number of simultaneously operational satellites refers specifically to those satellites operating in frequencies other than TT&C frequencies and does not include non-operational satellites that continue to operate in TT&C frequency bands as part of approved post-mission disposal plans. 13 See, e.g., ELS File No. 0024-EX-CN-2017, as modified 0055-EX-CM-2019. 14 As noted supra, starting with HE360 satellites in Cluster 9, HE360 plans to remove the S-band transmitter used to provide emergency backup, telemetry (2200-2290 MHz). 15 Deployment of satellites with different propulsion system characteristics, will require grant of a license modification. 16 See Mitigation of Orbital Debris in the New Space Age, Notice of Proposed Rulemaking, FCC 18-159, 33 FCC Rcd 11352 (2018); Mitigation of Orbital Debris in the New Space Age, Report and Order and Further Notice of Proposed Rulemaking, FCC 20-54, 35 FCC Rcd 4156 (2020).

HE360’s space-to-Earth and Earth-to-space operations shall be strictly limited to durations when the HE360 space stations referenced within this license request are visible to the corresponding earth station locations listed in Appendix A of the attachment to this grant, noting the additional restrictions within this grant. 8. We grant, on our own motion, a waiver of the U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), to allow non-conforming use of the 2200-2290 MHz band for HE360 to conduct telemetry and tracking,, subject to the condition that HE360 operates on a non-interference basis, accepts any interference from authorized services in these bands, and complies with the other conditions below regarding operations in these bands. HE360 intends to operate TT&C in these frequencies but will not operate in the EESS using this frequency band. The 2200-2290 MHz band is allocated to the space operation (space-to-Earth) and space research (space-to-Earth) services in the U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), for federal use only.17 In this instance we find good cause to waive the Table of Allocations to allow HE360 to operate command links only with its satellites based on HE360’s coordination with federal users in the frequency band. Additionally, HE360 shall be aware that non-Federal space-to-Earth transmissions in the 2200-2290 MHz are not permitted to earth stations within the US&P. Based on HE360’s coordination with federal users in the frequency band, which should ensure that any authorized federal users are protected from harmful interference, we find good cause to waive the U.S. Table of Frequency Allocations to allow HE360 to operate telemetry and tracking with its satellites in the 2200- 2290 MHz band. 9. On our own motion, we grant a waiver of the U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), for HE360 to conduct non-Federal space-to-space EESS operations at 2410 MHz with the first HE360 satellite cluster launched on December 3, 2018 only, subject to the condition that operations in this band do not cause harmful interference and that HE360 may not claim protection from interference. The 2400-2417 MHz band, inter alia, is allocated to the amateur service on a primary basis in the U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), for non-Federal use. 10. On our own motion, we grant a waiver of the U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), for HE360 to conduct non-Federal Earth-to-space operations in the 432-438 MHz band, with the first HE360 satellite cluster launched on December 3, 2018 only, subject to the condition that operations in this band do not cause harmful interference and that HE360 may not claim protection from interference. The 432-438 MHz band is allocated to the Earth exploration-satellite service (active) on a secondary basis in the U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), (c)(397), for Federal use only. 11. Power flux-density from HE360’s operations in the 8025-8400 MHz band must not exceed the limits in No. 22.5 and Table 21-4 of the International Telecommunication Union’s Radio Regulations. In addition, power spectral density levels at space research service earth stations from space-to-Earth operations in the 8025-8400 MHz band must not exceed the limits/protection criteria in Recommendation ITU-R SA.1157-1, and the guidelines for systems operating in the 8025-8400 MHz band in Recommendation ITU-R SA.1810 must be followed. 12. Operations pursuant to this license must not cause harmful interference to stations operating in the 2025- 2110 MHz band in accordance with the United States Table of Frequency Allocations. See 47 CFR § 2.106(a), (c)(347). 13. Transmissions in the 2025-2110 MHz, 8025-8400 MHz, and 2200-2290 MHz bands18 may only be made to/from earth stations coordinated with federal agencies, including National Aeronautics and Space Administration (NASA), Department of Commerce/National Oceanic and Atmospheric Administration (DOC/NOAA), and the United States Air Force Spectrum Management Office (AFSMO). Any use of Federal ground stations shall be coordinated by HE360’s federal government customers with AFSMO (jimmy.nguyen@us.af.mil), NASA (HQ-SatCoord@mail.nasa.gov) and DOC/NOAA (edna.prado@noaa.gov). A list of coordinated non-Federal earth stations is attached as Appendix A. HE360 shall provide the FCC with an updated list of coordinated non-Federal earth stations within ten business days following any changes to that list.19 Page 7 of 13 ATTACHMENT TO GRANT HawkEye 360, Inc. ICFS File Nos. SAT-MOD-20220906-00099, SAT-AMD-20221014-00136 14. Earth-to-space transmissions in the 2025-2110 MHz band to HE360 satellites must be coordinated with the SBE (Society of Broadcast Engineers). 15. Transmissions in the 2025-2110 MHz, 2200-2290 MHz, and 8025-8400 MHz bands are limited to the center frequencies and emission bandwidths coordinated with Federal users set forth in the Frequencies section of this grant. 16. In the 2025-2110 MHz band, HE360 shall comply with the following limitations: a. The primary uplink (Earth-to-space) emission bandwidths shall be limited to 170 kHz, 1.33 MHz, and 2.66 MHz. All uplink (Earth-to-space) 2.66 MHz emission bandwidth transmissions shall be limited to a duty cycle of no more than 10% per earth station per satellite. b. All uplink (Earth-to-space) transmissions to HE360 satellites using a center frequency of 2046.5 MHz and emission bandwidth of 1.33 MHz from any earth station located in the Northern hemisphere at latitudes greater than 60 degrees or in the Southern hemisphere at latitudes below 50 degrees (e.g. above 60N or below 50S) shall cease transmissions when the NASA PUNCH satellites (4 total) are within view of the respective earth station. c. All uplink (Earth-to-space) transmissions using center frequencies of 2064.965 MHz and 2065.965 MHz shall be limited to a duty cycle of less than 4% per earth station per satellite. d. All uplink (Earth-to-space) transmissions using center frequencies of 2053.0 MHz, 2053.7 MHz, 2077.4 MHz, and 2075.0 MHz shall cease transmissions during the Artemis-IV and later Artemis missions from launch to launch + 48 hours. 17. Power flux-density levels at the surface of the Earth resulting from space-to-Earth operation in the 2200- 2290 MHz band must not exceed the limits in Table 21-4 of the ITU Radio Regulations, and the power spectral density levels at space research service earth stations resulting from space-to-Earth operations in the 2200-2290 MHz band must not exceed the protection criteria in Recommendation ITU-R SA.1157-1 and Recommendation ITU-R SA.609-2. 18. All downlink (space-to-Earth) operations in the 2200-2290 MHz band shall be restricted to communication with earth stations identified in Appendix A that are located outside the US&P.20 19. In the event a spacecraft emergency requires activation of the emergency backup downlink (space-to- Earth) capability using center frequencies of 2242.0 MHz, 2254.0 MHz, or 2260.0 MHz, HE360 shall immediately notify the NASA JSC Spectrum Management (jsc-dl-spectrum-management@mail.nasa.gov) and Travis Inghram (HQ-SatCoord@mail.nasa.gov). Emergency backup downlink operations in the 2200-2290 MHz band shall be limited to spacecraft emergency situations only, and all other usage is not authorized. 20. All reception must comport with the requirements on unauthorized publication or use of communications in section 705 of the Communications Act of 1934, as amended (47 U.S.C. § 605). This license grant does not constitute an "authorization" with respect to the activities specified in section 705 of the Communications Act or in related provisions of chapter 119, Title 18, United States Code. 17 Although there are additional footnote allocations for non-Federal space research, space operations, and EESS, these non- federal allocations are limited to circumstances not relevant to HE360’s operations. See 47 CFR § 2.106(a)(c)(96) and (c)(303). 18 As noted supra, starting with HE360 satellites in Cluster 9, HE360 plans to remove the S-band transmitter used to provide emergency backup, telemetry downlinks (2200-2290 MHz). 19 A list of earth stations already coordinated with federal agencies is attached as Appendix A to this grant. 20 See also condition 8.

The U.S. Table of Frequency Allocations, Section 2.106(a), is waived with respect to reception of ADS-B signals in the 1087.7-1092.3 MHz frequency band, for satellites through Cluster 8. This band was allocated internationally for the aeronautical mobile-satellite (R) service (AMS(R)S) (Earth-to-space) on a primary basis, at WRC-15, and is limited to the space station reception of ADS-B emissions from aircraft transmitters that operate in accordance with recognized international aeronautical standards. Stations operating in the AMS(R)S shall not claim protection from stations operating in the aeronautical radionavigation service. Resolution 425 (WRC-15) shall apply.21 Any future protection of ADS-B reception will be governed by the relevant status in the Table of Frequency Allocations and must be in accordance with any subsequent rulemaking proceedings to implement any new domestic allocations or service rules. 22. The U.S. Table of Frequency Allocations, Section 2.106(a), is waived with respect to reception of AIS signals in the 156.7625-156.7875 MHz (AIS 3), 156.8125-156.8375 MHz (AIS 4), 161.9625-161.9875 MHz (AIS 1) and 162.0125-162.0375 MHz (AIS 2).22 As a condition of this waiver, HE360 must not claim protection for reception of messages in the 156.0125-162.0375 MHz frequency band that is not in accordance with the Table of Frequency Allocations for the pertinent area and may only claim protection to the extent provided by the status of the reception under the Table of Frequency Allocations. 23. HE360 may claim protection for reception in the 156.7625-162.0375 MHz band only to the extent permitted under the U.S. Table of Frequency Allocations for domestic operations or the ITU Radio Regulations for international operations, as of the time of operation. Operations in the 156.7625-162.0375 MHz band must be in accordance with any Commission rulemakings subsequent to the release of this license that implement any new domestic allocations or service rules for these bands.23 24. The U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), is waived with respect to reception of the DSC signal in the 156.5125-156.5375 MHz frequency band on a non-conforming, non-harmful interference basis. The 156.5125-156.5375 MHz frequency band is allocated to Maritime Mobile on a primary basis for non-Federal operations and in all ITU Regions.24 In the United States, there is also limited use of this band by certain grandfathered public safety radio pool licensees.25 As a condition of this waiver, HE360 must not claim protection for reception of messages in the 156.5125-156.5375 MHz frequency band that is not in accordance with the Table of Frequency Allocations for the pertinent area and may only claim protection to the extent provided by the status of the reception under the Table of Frequency Allocations. 25. The U.S. Table of Frequency Allocations, 47 CFR § 2.106(a), is waived with respect to reception of EPIRB signals in the 406-406.1 MHz frequency band. The 406-406.1 MHz frequency band is allocated for Mobile-Satellite Service (MSS) and is limited to low-power satellite emergency position-indicating radio beacons 21 We previously found good cause to waive sections 2.102(a) and 2.106 to permit reception of ADS-B messages on an unprotected basis in the United States because doing so will not cause any interference or unreasonably preclude other services, and make the same finding with respect to Cluster 8. 22 We previously found that the reception of AIS transmissions cannot cause harmful interference, and these transmissions will be present pursuant to existing authorizations using frequencies allocated to other services regardless of whether they are received by a HE360 satellite. We also concluded that the service HE360 proposes will serve the public interest by providing critical near real-time maritime data of interest for both government and commercial users. We make the same findings with respect to Clusters 8 and 9. 23 Iridium Order and Authorization, 31 FCC Rcd at 8689, para. 50. 24 47 CFR § 2.106(a), (b)(111), (266), and (c)(52). 25 47 CFR § 2.106(a), (c)(266). We found that the reception of DSC transmissions cannot cause harmful interference, and these transmissions will be present pursuant to existing authorizations using frequencies allocated to other services regardless of whether they are received by a HE360 satellite. We also concluded that the service HE360 proposes will serve the public interest by providing near real-time maritime safety data. Exhibit A: Narrative at 44. We make the same findings with respect to Clusters 8 and 9. Page 9 of 13 ATTACHMENT TO GRANT HawkEye 360, Inc. ICFS File Nos. SAT-MOD-20220906-00099, SAT-AMD-20221014-00136 (EPIRB).26 As a condition of this waiver, HE360 must not claim protection for reception of messages in the 406- 406.1 MHz frequency band that is not in accordance with the Table of Frequency Allocations for the pertinent area and may only claim protection to the extent provided by the status of the reception under the Table of Frequency Allocations. 26. The U.S. Table of Frequency Allocations, § 2.106(a), is waived, to the extent necessary, with respect to reception of signals transmitted from terrestrial sources (Earth-to-space) in frequency bands used by the Global Positioning System (GPS). The frequency bands used by the GPS are allocated for Space-to-earth transmissions.27 27. HE360’s request for a waiver of the U.S. Table of Frequency Allocations, 47 CFR § 2.106(a),28 with respect to reception of inter-satellite signals from the Inmarsat satellite system in the 1525-1544 MHz and 1545- 1559 MHz frequency bands is GRANTED, on an unprotected, non-interference basis.29 Although the allocations in this frequency band do not include a directional indicator for space-to-space communications, reception by the HawkEye satellites of these frequencies will not in any way alter the interference environment, as the received signal will be indistinguishable in its technical characteristics from signals transmitted in the allocated space-to- Earth direction. 28. HE360’s request for a waiver of the Table of Frequency Allocations, 47 CFR § 2.106(a), to receive inter- satellite signals from the Inmarsat satellite system in the 1626.5-1645.5 and 1646.5-1660.5 MHz frequency bands on an unprotected, non-interference basis, is GRANTED.30 Additionally, we grant on our own motion waiver to of the Table of Frequency Allocations, 47 CFR § 2.106(a), to transmit inter-satellite signals to the Inmarsat satellite system in the 1626.5-1645.5 MHz and 1646.5-1660.5 MHz frequency bands on an unprotected, non- interference basis. The allocation for the Mobile-Satellite Service in which the Inmarsat system operates and that encompasses these bands does not include a space-to-space directional indicator. HE360 states that transmission on a non-conforming basis in the L-band frequencies will occur only on frequencies that Inmarsat assigns to the spaceborne Inmarsat BGAN terminals onboard the HE360 spacecraft. HE360 states that transmission on a non- conforming basis in the L-band frequencies will occur only on frequencies that Inmarsat assigns to the spaceborne Inmarsat BGAN terminals onboard the HE360 spacecraft. HE360 notes that these transmissions are approved and supported by Inmarsat and fall within its licensed spectrum.31 As with its other operations, Inmarsat will assign channels to the spacecraft consistent with its coordination agreements with other operators in the band, 26 47 CFR § 2.106(a), (b)(266). We found that the reception of EPIRB transmissions cannot cause harmful interference, and these transmissions will be present pursuant to existing authorizations using frequencies allocated to other services regardless of whether they are received by a HE360 satellite. We also concluded that the service HE360 proposes will serve the public interest by augmenting existing COSPAS-SARSAT architecture used to monitor and geolocate EPIRB distress signals. We make the same findings with respect to Clusters 8 and 9. The SARSAT (Search and Rescue Satellite Aided Tracking) system is operated by NOAA to detect and locate mariners, aviators, and recreational enthusiasts in distress. It uses NOAA satellites in low-earth and geostationary orbit to detect and locate distress signals and relay them from emergency beacons to a network of ground stations and the U.S. Mission Control Center, which processes the signals and alerts appropriate search and rescue authorities. SARSAT is part of the international COSPAS-SARSAT program. See http://www.sarsat.noaa.gov. 27 We found that the reception of transmitted signals from terrestrial sources (Earth-to-space) in frequency bands used by the Global Positioning System (GPS) cannot cause harmful interference to actual GPS (Space-to earth) operations. We make the same findings with respect to Clusters 8 and 9. 28 We note that waiver of 47 CFR § 25.112(a)(3) is unnecessary as this provision was removed from the Commission's rules effective Jan. 5, 2024. See Space Innovation; Expediting Initial Processing of Satellite and Earth Station Applications, Report and Order and Further Notice of Proposed Rulemaking, FCC 23-73 (Sept. 22, 2023) at para. 27; 88 Federal Register 84737 (Dec. 6, 2023). 29 See Legal Narrative at 8-9. 30 Legal Narrative at 8. 31 Id. at 9.

SAT-MOD-20220906-00099, SAT-AMD-20221014-00136 ensuring that there is no harmful interference between these systems.32 Inmarsat will maintain the same extent of positive control of HE360’s operations as it does for its other L-band users and will thereby be able to address any unlikely interference issues as required by Section 25.287 of the Commission’s Rules. 29. HE360 must maintain a U.S. point of contact available by telephone 24 hours per day, seven days per week, with the authority and ability to terminate operations authorized herein. The telephone number for this U.S. point of contact must also be provided to NTIA (ravery@ntia.doc.gov), DOC/NOAA (edna.prado@noaa.gov), and NASA (HQ-SatCoord@mail.nasa.gov). 30. HE360 shall provide the FCC and other federal agencies the initial orbital parameters (e.g. operating altitudes, inclination angle) for each cluster within 30 days following launch. Notification shall be provided to AFSMO (jimmy.nguyen@us.af.mil), NASA (HQ-SatCoord@mail.nasa.gov) and DOC/NOAA (edna.prado@noaa.gov). 31. Given the opportunity for additional entrants to operate in HE360’s requested frequency bands, this grant includes the previously-granted waiver to HE360 of the modified processing round requirements of 47 CFR §§ 25.156 and 25.175.33 32. Because HE360 must comply with the technical requirements in Part 2 of the Commission’s rules and the above-referenced power flux-density limits, which should prevent harmful interference to other operators in the band, this grant includes the previously-granted waiver of the default service rules in 47 CFR § 25.217(b).34 33. This license will become null and void if, at any time during the license term, there are no HE360 satellites operating. 34. In connection with the provision of service in any particular country, HE360 is obliged to comply with the applicable laws, regulations, rules, and licensing procedures of that country 35. HE360’s three Pathfinder satellites were successfully launched on December 3, 2018 and are operational. See ELS File No. 0024-EX-CN-2017. Authorization for continued operations of the three Pathfinder satellites under Part 25 of the Commission’s rules is included in this grant. We find that warehousing concerns are addressed in this situation through the imposition of condition 25 above. Thus, we decline to impose milestone and bond obligations on HE360. 36. HE360 must coordinate physical operations of spacecraft with any operator using similar orbits, for the purposes of eliminating collision risk and minimizing operational impacts. The orbital parameters specified in this grant are subject to change based on such coordination. 37. HE360 must provide a semi-annual report, by January 1 and July 1 each year, covering the preceding six month period, respectively, from June 1 to November 30 and December 1 to May 31. The report should include the following: Number of conjunction events identified for any HE360 system satellites during the reporting period, and the number of events that resulted in an action (maneuver or coordination with another operator), as well as any difficulties encountered in connection with the collision avoidance process and any measures taken to address those difficulties. HE360 must report any loss of control of HE360 satellites at altitudes above 350 km not less than 10 days following the loss of control. Based on the information reported, the license may be subject to additional terms and conditions, including additional reporting obligations, limitations on additional deployments, requirements for early removal of satellites from orbit, or any other appropriate conditions to limit collision risk. In the event of HE360 satellite 32 Id. 33 See DigitalGlobe, Inc., Order and Authorization, 20 FCC Rcd 15696 (Sat. Div., Int’l Bur. 2005) at para. 8. 34 Id., 20 FCC Rcd at 15702-03, para. 19.

HE360 must communicate and collaborate with NASA to support safety of both HE360 and NASA assets and to preserve long-term sustainable space-based communications services. HE360 must report on the progress of its communications and collaboration efforts to the Commission in its regular reports specified in condition 27, above. HE360 must coordinate and collaborate with NASA to promote a mutually beneficial space environment that would minimize impacts to NASA’s science missions involving astronomy. 39. HE360 must coordinate with NSF to achieve a mutually acceptable agreement to mitigate the impact of its satellites (call sign S3165) on optical ground-based astronomy. HE360 must submit an annual report to the Commission, by January 1st each year covering the preceding year (1) describing whether it has reached a coordination agreement with NSF addressing optical astronomy; and (2) any steps HE360 has taken to reduce the impact of its satellites on optical astronomy. If HE360 provides a statement in the record that NSF has no concerns within 45 days following deployment of the HE360 satellites to approximately 590 km, no further reporting will be required. 40. The license term is 15 years, calculated from the deployment of the three Pathfinder satellites on December 3, 2018 (that is December 3, 2033). 41. Within 30 days after deployment of each satellite pursuant to this license, HE360 must file a notification with the Commission specifying its apogee and perigee altitudes and orbital inclination. Licensee/grantee is afforded thirty (30) days from the date of release of this action to decline the grant as conditioned. Failure to respond within this period will constitute formal acceptance of the grant as conditioned. This action is taken pursuant to Section 0.261 of the Commission’s rules on delegated authority, 47 CFR § 0.261, and is effective upon release. Station licenses are subject to the conditions specified in Section 309(h) of the Communications Act of 1934, as amended, 47 U.S.C. § 309(h).
