       Re:     Request for Special Temporary Authority
               Hagerstown, Maryland Earth Station E000296

Dear Ms. Dortch:

Intelsat License LLC (“Intelsat”) herein requests a grant of Special Temporary Authority (“STA”) 1 for
30 days, commencing May 31, 2019, to use its Hagerstown, Maryland C-band earth station (Call Sign
E000296) to provide launch and early orbit phase (“LEOP”) services for the Yamal-601 satellite.
Yamal-601 is expected to launch on May 31, 2019.2 Intelsat expects the LEOP period to last
approximately 30 days.

The Yamal-601 LEOP operations will be performed at the following frequencies: 5852.0 MHz and
5920.0 MHz (LHCP, V, H) in the uplink, and 4199.0 MHz and 4199.9 MHz (RHCP, V, H) 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.3 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 Yamal-601 LEOP mission is as follows:

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

         Intelsat has filed its STA request, FCC Form 159, a $210.00 filing fee, and this supporting
letter electronically via the International Bureau’s Filing System (“IBFS”).
       The in-orbit testing location for Yamal-601, which Intelsat understands is licensed by the
Russian Federation, will be 48.8° E.L. The satellite’s final location will be 49° E.L.
       Thales Alenia Space France (“Thales”), the manager of the Yamal-601 mission, will handle
the coordination.

Request to speak with Harry Burnham or Kevin Bell.

In further support of this request, Intelsat herewith attaches Exhibit A, which contains waiver requests.
In the 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 Yamal-601 LEOP mission, 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 request will allow Intelsat to help launch the Yamal-601 satellite. This will help
provide services at the 49° E.L. location and thereby promotes the public interest.

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

Respectfully submitted,

/s/ Cynthia J. Grady
