Re:    Request for Extension of Special Temporary Authority for New
       Dawn; Call Sign: S2751

Dear Ms. Dortch:

Intelsat New Dawn Company, Ltd. ("Intelsat") herein requests a 14-day
extension – through July 10, 2011 – of the Special Temporary
Authority ("STA")1 previously granted Intelsat to temporarily operate
its New Dawn satellite (call sign S2751) at 32.85º E.L. in the bands
3625-4200 MHz (downlink), 5850-6500 MHz (uplink), 10950-11200
MHz and 11450-11700 MHz (downlink), and 14000-14500 MHz
(uplink) during traffic transition and subsequently to drift the satellite
to its permanent location of 32.8° E.L.2 New Dawn currently is
located at 32.85° E.L. Intelsat seeks this STA extension in order to
ensure safe station-keeping of New Dawn and Galaxy 11 during traffic
transition, as explained more fully below.

New Dawn was launched on April 22, 2011. Shortly thereafter, Intelsat
determined that the satellite’s west antenna reflector had not
successfully deployed. As a result, two of the satellite’s thrusters
currently are not useable, which has resulted in some uncertainty
regarding the satellite’s maneuver performance. Accordingly, during
traffic transition from Galaxy 11, which currently is located at 32.8°

  Intelsat has filed this STA request, an FCC Form 159 and an $860.00
filing fee electronically via the International Bureau's Filing System.

  See Policy Branch Information; Actions Taken, Report No. SAT-
00783, File No. SAT-STA-20110519-00091 (June 3, 2011) (Public
Notice). New Dawn is licensed to permanently operate at 32.8° E.L.
See Policy Branch Information; Actions Taken, Report No. SAT-
00574, File No. SAT-LOA-20080509-00101 (Jan. 16, 2009) (Public
Notice); Policy Branch Information; Satellite Space Applications
Accepted for Filing, Report No. SAT-00752, File No. SAT-MOD-
20101029-00228 (Jan. 21, 2011) (Public Notice). During the drift from
32.85º E.L. to 32.8º E.L., the satellite’s communications payload will
be operated.

E.L.,3 Intelsat plans to continue to employ a more conservative
separation strategy, including separating the two satellites slightly in
longitude to allow for uncertainties in the maneuvers. Traffic transition
is expected to be completed by early July.

Intelsat has assessed and limited the probability of the space station
becoming a source of debris as a result of collision with large debris or
other operational space stations while temporarily located at 32.85º
E.L. With the exception of Galaxy 11, New Dawn will not be located
at the same orbital location as another satellite or at an orbital location
that has an overlapping station-keeping volume with another satellite.
Galaxy 11 is scheduled to move on July 2, 2011, pending completion of
traffic transition.4 Further, Intelsat is not aware of any other FCC
licensed system, or any other system applied for and under
consideration by the FCC, having an overlapping station-keeping
volume with New Dawn. Finally, Intelsat is not aware of any system
with an overlapping station-keeping volume with New Dawn that is the
subject of an ITU filing and that is either in orbit or progressing
towards launch.

The Commission may grant a request for STA when there are
extraordinary circumstances requiring temporary operations in the
public interest.5 Due to the uncertainty regarding New Dawn’s
maneuver performance, temporary operation of the satellite at 32.85º
E.L. is a critical step in ensuring the safe station-keeping of New Dawn
and Galaxy 11 while traffic transition occurs. This, in turn, will ensure
continuity of service to customers at the 32.8° E.L. location, and
thereby promotes the public interest.

  Following traffic transition, Galaxy 11 will be relocated to 55.5° W.L.
