         Re:       Requestfor Special Temporary Authorityfor In—Orbit Testing of
                   DIRECTV 14 and DIRECTVY RB—1 at 76° W.L.

 Dear Ms. Dortch:

         DIRECTV Enterprises, LLC ("DIRECTV") hereby requests Special Temporary
 Authority ("STA") to locate the DIRECTV 14 satellite (call sign $2869) along with the
 DIRECTV RB—1 payload (call sign $2711) at the 76° W.L. orbital location for in—orbit
 testing ("IOT") after launch of the satellite, which is currently scheduled for December 4,
 2014. This STA will cover a period of approximately 30 days within a 60 day window,
 which DIRECTV requests be keyed to become effective upon the satellite‘s arrival at 76°
 W.L.

         DIRECTV 14 is currently at the launch site being readied for launch. DIRECTV
 desires 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 14 will be located at 76°
               W.L. [no earlier than about December 14, 2014].

         «_    After DIRECTV 14 reaches 76° W.L., DIRECTV will then commence IOT of
               the satellite for approximately 4 weeks.‘

         °_    After IOT is completed, DIRECTV 14 will then be drifted to its assigned
               location at 99° W.L. (nominal) over the course of approximately 23 days
               [reaching that orbital position on or about February 5, 2015].

 \   During the period covered by this STA, DIRECTV will use 28351.0 and 28353.0 MHzfor its
     command uplinks and 18799.0 and 18799.5 MHz for its telemetry downlinks.

In order to address the timing uncertainties normally associated with positioning a
spacecraft after launch, DIRECTV requests that the STA become effective upon the
arrival of DIRECTV 14 at 76° W.L.

            Operation and testmg ofDIRECTV 14 and DIRECTV RB—1 during IOT will
consist of performance venficatlon testlng of all transponders and antenna pattern
verification testing of all antennabeaims. ‘During this testing, unmodulated CW carriers
will be used to generate swept frequency response and gain transfer characteristics of
each transponder The maximumvalueof transmit power used durmg this testing will be
consistent with the DIRECTV14 and DIRECTV RB—1 applications," except for short
periods of time during gain transfer when the maximum transmit power for DIRECTV 14
could exceed that value by up to 10 dB during some tests." This testing will not result in
harmful interference to other Ka—band satellite systems as the closest co—frequency
operational satellite is located 9° away. Nor will this testing result in harmful
interference to any DBS satellite system as the closest co—frequency operational DBS
satellite is located 1° away and, as demonstrated in the measured transmit antenna gain
submission for DIRECTV RB—1, the 17/24 GHz BSS payload on DIRECTV 14 will not
exceed the —1 17 dBW/m*/100kHz PFD coordination trigger beyond 0.12°.4 DIRECTV
will also coordinate its TT&C operations with all other potentially affected operators to
ensure that no harmful interference results. Furthermore, DIRECTV is prepared to
terminate all testing 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
test the DIRECTV 14/RB—1 satellite to ensure that it is fully operational and ready to
begin providing service to millions of DIRECTV subscribers from the satellite‘s licensed
orbital location. Allowing DIRECTV to test the satellite at 76° W.L. will serve the
public interest by minimizing the risk of interference.

>      Note that, as with IOT testing of DIRECTV 10, 11 and 12, all DIRECTV 14 IOT testing will
       be closely coordinated with U.S. government systems under FN US334.

       Accordingly, and in light of the impending launch date, DIRECTV requests the
expeditious grant of special temporary authority.
