Re: Skybox Imaging, Inc., IBFS File No. SAT-LOA-20111222-00246 (Call Sign: S2851) 
Dear Mr. Baruch:
This letter dismisses, as unacceptable for filing, the above-referenced application for 
launch and operating authority for two non-geostationary-orbit (NGSO) Earth Exploration 
Satellite Service (EESS) space stations filed by Skybox Imaging, Inc. (Skybox).1  
Section 25.112(a) of the Commission’s rules states that an application will be returned as 
unacceptable for filing if it is not substantially complete and consistent with the Commission’s 
rules.2 Skybox’s NGSO EESS application fails to provide information required by three 
provisions of the Commission’s rules: (1) the predicted gain contours required by Section 
25.114(d)(3); (2) a link performance analysis required by Section 25.114(d)(4) for the second of 
Skybox’s two NGSO EESS satellites, SkySat-2; and (3) downlink power flux density (PFD) 
levels for SkySat-2, required by Section 25.114(c)(8).3  See 47 C.F.R. §§ 25.114(c)(8), (d)(3), & 
(d)(4).  Accordingly, we dismiss Skybox's application, without prejudice to re-filing.
We note that Skybox states that SkySat-2 will operate with an altitude in the range of 450 
to 637 km, and that the exact orbit of SkySat-2 will be determined at a future date.4 In any re-
filed application, Skybox should submit information sufficient to address the full range of 
  
1 If Skybox re-files an application identical to the one dismissed, with the exception of supplying the 
corrected information, it need not pay an application fee.  See 47 C.F.R. § 1.1111(d).
2 47 C.F.R. § 25.112(a).
3 With respect to the link budget and PFD for SkySat-2, we would consider appropriate a link budget 
calculated based on the highest anticipated orbital altitude and a downlink PFD levels calculated based on 
the lowest anticipated orbital altitude.

possible altitudes for Skybox 2.  Manned spacecraft, including the International Space Station, 
may operate at the lower end of the range of altitudes specified for SkySat-2.  Accordingly, any 
re-filed request for approval for low-earth orbit operations must include the full range of 
measures (such as maintaining a minimum distance separation) and coordination that will be 
undertaken to address risks to inhabitable orbiting objects.5
