W WILTSHIRE & GRANNIS ur December 1, 2009 Marlene H. Dortch Secretary Federal Communications Commission 445 Twelfth Street, S.W. Washington, DC 20554 Re: Requestfor Special Temporary Authorityfor In—Orbit Drift of DIRECTV 12from 76° W.L. to 103° W.L. Call Sign: $2797 Dear Ms. Dortch: DIRECTV Enterprises, LLC ("DIRECTV") hereby requests Special Temporary Authority ("STA") to drift the DIRECTV 12 satellite from the 76° W.L. orbital location to the location it has requested for licensing at 103° W.L. (nominal). DIRECTV intends to conduct in—orbit testing ("IOT") of DIRECTV 12 after launch of the satellite, which is currently scheduled for late December 2009. This STA will cover the use of Ka—band frequencies for telemetry, tracking and command ("TT&C") functions for a period commencing upon completion of IOT at 76° W.L. through migration of the satellite to its requested position at the nominal 103° W.L. location. DIRECTV will use 29255.00 and 29497.00 MHz for its command uplinks and 18302.25 and 18302.75 MHz for its telemetry downlinks. DIRECTV anticipates that this relocation process will occur over a period of approximately 20 days, and requests that this STA be keyed to become effective upon completion of IOT at 76° W.L. DIRECTV 12 is currently at the launch site being readied for launch later this month. DIRECTV intends to conduct IOT for approximately four weeks before moving the satellite to its licensed position to begin commercial operations. Specifically, DIRECTV contemplates the following schedule, with approximate dates indicated in [brackets]: + After launch and orbit raising maneuvers, DIRECTV 12 will be located at 76° W.L. [no earlier than February 15, 2010]. _ After DIRECTV 12 reaches 76° W.L., DIRECTV will then commence IOT of the satellite for approximately four weeks.

WILTSHIRE & GRANNIS LLP Marlene H. Dortch December 1, 2009 Page 2 of 2 + After IOT is completed, DIRECTV 12 will then be drifted to its assigned location over the course of approximately 20 days [reaching that orbital position no later than May 5, 2010]. Operation of the TT&C functions of DIRECTV 12 during this maneuver will not result in harmful interference to other satellite systems. DIRECTV will coordinate its TT&C operations during drift with all other potentially affected operators to ensure that no harmful interference results. Furthermore, DIRECTV is prepared to terminate all operations immediately upon notification from the Commission that its operations cause harmful interference to any authorized user of the spectrum. Grant of this STA request will serve the public interest by allowing DIRECTV to relocate the DIRECTV 12 satellite to its licensed orbital location after testing to ensure that it is fully operational and ready to begin providing service to millions of DIRECTV subscribers. Accordingly, and in light of the impending launch date, DIRECTV requests the expeditious grant of special temporary authority. Respectfully submitted, AQt.M ult William M. Wiltshire Counsel to DIRECTYV Enterprises, LLC
