          Re:     Request for Extension of Special Temporary Authority
                  Hagerstown, Maryland Earth Station KA275

Dear Ms. Dortch:

Intelsat License LLC (“Intelsat”) herein requests an additional 30 days of Special Temporary Authority
(“STA”)1 previously granted Intelsat to use its Hagerstown, Maryland C-band earth station—call sign
KA275—to provide launch and early orbit phase (“LEOP”) services2 for the Bangabandhu-1 (“BS-1”)
satellite. Due to delays, BS-1 is now expected to be launched on May 7, 2018.3 Intelsat expects the
LEOP period to last approximately 30 days.

The BS-1 LEOP operations will be performed at the following center frequencies: 5850.0 MHz and
6425.0 MHz (LHCP) in the uplink, and 3703.0 MHz and 4199.8 MHz (CP) in the downlink. The LEOP
operations will be coordinated with all operators of satellites that use the same frequency bands and are
in the LEOP path.4 All operators of satellites in that path will be provided with an emergency phone
number where the licensee can be reached in the event that harmful interference occurs.

The 24x7 contact information for the BS-1 LEOP mission is as follows:

Ph.:      (703) 559-7701 – East Coast Operations Center (primary)
          (310) 525-5591 – West Coast Operations Center (back-up)

Request to speak with Harry Burnham or Kevin Bell.

In further support of this extension request, Intelsat incorporates by reference Exhibits A and B
submitted with its original STA request, which contain a coordination report and waiver requests. In the

 Intelsat has filed its STA request, FCC Form 159, a $200.00 filing fee, and this supporting letter electronically
via the International Bureau’s Filing System (“IBFS”).

 The in-orbit testing and final orbital location for BS-1, which Intelsat understands is licensed by Bangladesh,
will be 119.1° E.L.

    Thales Alenia Space, the manager of the BS-1 mission, will handle the coordination.

extremely unlikely event that harmful interference should occur due to transmissions to or from its earth
station, Intelsat will take all reasonable steps to eliminate the interference.

Finally, Intelsat clarifies that during the BS-1 LEOP mission, Thales Alenia Space (“Thales”) will serve
as the mission manager. Thales will build and send the commands to the Intelsat antenna, which will
process and execute the commands. Telemetry received by Intelsat will be forwarded to Thales. Intelsat
will perform the ranging sessions by sending a tone to the spacecraft periodically. Intelsat will remain in
control of the baseband unit, RF equipment, and antenna.

Grant of this STA extension request will allow Intelsat to help launch the BS-1 satellite. This will help
provide services at the 119.1° E.L. location and thereby promotes the public interest.

Please direct any questions regarding this STA extension request to the undersigned at (703) 559-6949.

Respectfully submitted,

/s/ Cynthia J. Grady
