  (Call Sign S2682)
Dear Mr. Drucker:
This letter refers to the above-referenced application filed by ATCONTACT Communications, 
LLC (ATCONTACT). ATCONTACT seeks to modify its license by modifying the assigned location of
one of the geostationary fixed-satellite service (GSO FSS) satellites in its licensed system from 34° W.L. 
to 77° W.L.1  As set forth below, we dismiss the application as incomplete without prejudice to refiling. 
Section 25.112(a)(2) of the Commission’s rules states that an application that does not 
substantially comply with the Commission’s rules will be returned to the applicant as unacceptable for 
filing unless the application is accompanied by a waiver request with reasons supporting the waiver.2  
Section 25.210(c) requires all fixed-satellite service space stations to have a minimum capability to 
change transponder saturation flux densities by ground command in 4 dB steps over a range of 12 dB.3  
ATCONTACT’s application failed to include the required information on gain step capabilities for its 
space station.  Moreover, ATCONTACT did not request a waiver of this rule. Accordingly, 
ATCONTACT’s application to modify the assigned orbital location of its GSO satellite to 77° W.L., File 
No. SAT-MOD-20061115-00139, is dismissed without prejudice to refiling.4
Further, although not grounds for dismissal, we note that ATCONTACT may wish to address 
several additional issues if it chooses to refile.  ATCONTACT’s application included a showing pursuant 
to section 25.114(d)(14)(iii) of the rules concerning its assessment of whether there are any known 
satellites at, or reasonably expected to be located at, the requested orbital location.5 ATCONTACT’s 
application states that “[c]urrently there are no other operational satellites at 77° W. L.”6 It is our

if the resubmitted application is identical to the returned application except for the missing information.  See 47

understanding, however, that the EchoStar-4 satellite is operating at the 77° W.L. orbital location.7  
Consequently, ATCONTACT should provide, in any refiled application, any additional analysis or 
information that may be relevant if our understanding is correct, and an explanation of the method used to
make the assessment provided for by the Commission’s rules.8   
In addition, ATCONTACT states that it could accommodate co-location at the 77° W.L. orbital 
location by “flying at non-zero inclination and eccentricity ... assuming the other satellite is kept to a tight 
zero-degree box."9 To expedite processing of any refiled application, ATCONTACT should include 
additional information as to the specific technical parameters intended by the term “tight zero degree 
box,” and an assessment of whether the assumption represents a realistic assumption for space station 
operations.  
Accordingly, pursuant to Section 25.112(a)(1) of the Commission’s rules, 47 C.F.R.  
§ 25.112(a)(1), and Section 0.261 of the Commission’s rules on delegations of authority, 47 C.F.R.  
§ 0.261, we dismiss ATCONTACT’s application without prejudice to refiling.
Sincerely,
Robert G. Nelson
Chief, Satellite Division
