        Re:       Requestfor Special Temporary Authorityfor In Orbit Testing ofDIRECTVY 10
                  to 102.6° W.L.

Dear Ms. Dortch:

         On May 25, 2010, DIRECTV Enterprises, LLC ("DIRECTV") filed a request for Special
Temporary Authority ("STA") to repeat an abbreviated set of in—orbit tests on the DIRECTV 10
satellite (call sign $2641) at the 102.6° W.L. orbital location.‘ Unfortunately, DIRECTV
omitted from that filing a request that the STA include authority to relocate the satellite back to
its licensed position at 102.815° W.L., and to resume commercial operations during its migration
to that location. DIRECTV requests that the STA include such authority, and expects to be able
to complete all activities under the STA (including relocation) within the 30—day period
originally requested.

         As DIRECTV has previously informed the Commission, it intends to perform certain
ameliorative procedures and in—orbit testing on DIRECTV 10 at the 102.6° W.L. location. Once
that process is complete, DIRECTV intends to return DIRECTV 10 to its licensed location, and
to return CONUS traffic from DIRECTV 12 to DIRECTV 10 over the course of this migration.
Operation of DIRECTV 10 during this maneuver will not result in harmful interference to other
satellite systems as DIRECTV 10 will be operating in accordance with the technical parameters
of its existing authorization (except of course for the orbital location). The only other co—
frequency satellites located within two degrees of arc are DIRECTV 8, DIRECTV 9S8, and
DIRECTV 12, operating at 100.85° W.L., 101.1° W.L., and 102.765° W.L., respectively.
DIRECTV anticipates no difficulty in coordinating the operations of its own satellites.
DIRECTV will also 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 ensuring a smooth and
expedited return of DIRECTV 10 to its authorized location, where it can resume commercial

service to millions of DIRECTV subscribers as soon as possible. Accordingly, DIRECTV
requests the expeditious grant of the STA, including the additional authority requested herein.
