December 31, 2018 Ms. Marlene H. Dortch Secretary Federal Communications Commission 445 12th Street, SW Washington, DC 20554 Re: Requests for Special Temporary Authority Fillmore, California Earth Station E4132 Riverside, California Earth Station E040125 Dear Ms. Dortch: Intelsat License LLC (“Intelsat”) herein requests a grant of Special Temporary Authority (“STA”)1 for 30 days, commencing January 21, 2019, to use its Fillmore, California C-band earth station (Call Sign E4132) and its Riverside, California earth station (Call Sign E040125) to provide launch and early orbit phase (“LEOP”) services for the GSAT-31 satellite. GSAT-31 is expected to launch on January 21, 2019.2 Intelsat expects the LEOP period to last approximately 10 days. The GSAT-31 LEOP operations will be performed at the following frequencies: 6415.000 MHz and 6423.496 MHz (CP) in the uplink; and 4188.768 MHz and 4196.928 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.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 GSAT-31 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. 1 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”). 2 The in-orbit testing and final location for GSAT-31, which Intelsat understands is licensed by India, will be 48.0° E.L. 3 Indian Space Research Organisation (“ISRO”), the manager of the GSAT-31 mission, will handle the coordination.

Ms. Marlene H. Dortch December 31, 2018 Page 2 In further support of this request, Intelsat herewith attaches Exhibits A-C, which contain coordination reports and 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 GSAT-31 LEOP mission, ISRO will serve as the mission manager. ISRO 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 ISRO. 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 GSAT-31 satellite. This will help provide services at the 48.0° 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 Cynthia J.
