Re:  EchoStar Satellite Operating Corporation
 File No. SAT-MOD-20061218-00154
Call Sign: S2636
Dear Mr. Moskowitz:
This letter is in response to EchoStar Satellite Operating Corporation’s (EchoStar) above 
referenced modification application specifying a precise orbital location for the EchoStar 113 
satellite.  EchoStar filed this application to meet a condition contained it its October 19, 2006 
authorization for this satellite.1 For the following reason, we dismiss the application as 
incomplete without prejudice to refiling. 
Section 25.112(a)(2) of the Commission’s rules states that an application is unacceptable 
for filing if it “does not substantially comply with the Commission’s rules [or] regulations.”2
Further, section 25.114(d)(14)(iii) provides that a space station operator must include a statement 
that it has assessed whether there are any known satellites at, or reasonably expected to be located 
at, the requested orbital location, and if so, provide the identities of the parties and measures 
taken to prevent collisions.3 EchoStar did not submit this information for its proposed operations 
at 112.85° W.L. Consequently, the modification application is incomplete and therefore 
unacceptable for filing.

00248 and SAT-AMD-20060724-00081, grant stamped with conditions by the Chief, Satellite Division, 
October 19, 2006.

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 the application without prejudice to refiling. EchoStar has 15 days from date 
of this letter to refile its complete modification application.4  Failure to submit this information 
may render EchoStar’s authorization for the 113° W.L. orbital location null and void. 
Sincerely,
Robert G. Nelson
Chief, Satellite Division
