August 24, 2016 Ms. Marlene H. Dortch Secretary Federal Communications Commission 445 12th Street, S.W. Washington, D.C. 20554 Re: Request for Special Temporary Authority 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 October 4, 2016, to use its Riverside, California C-band earth station—call sign E040125—to provide launch and early orbit phase (“LEOP”) services for the GSAT-18 satellite. GSAT- 18 is expected to be launched October 4, 2016.2 The LEOP period is expected to last approximately 10 days.3 The GSAT-18 LEOP operations will be performed in the following frequency bands: 6415.00 MHz and 6421.48 MHz in the uplink (RHCP), and 4187.52 MHz and 4155.768 MHz in the downlink (LHCP). 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 GSAT-18 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, an FCC Form 159, a $195.00 filing fee, and this supporting letter electronically via the International Bureau’s Filing System (“IBFS”). 2 The permanent orbital location for GSAT-18, which Intelsat understands is licensed by India, will be 74.0° E.L. The in-orbit testing location will be 48.0° E.L. 3 Intelsat is seeking authority for 30 days to accommodate a possible launch delay. 4 Indian Space Research Organisation (“ISRO”), the manager of the GSAT-18 mission, will handle the coordination.

Ms. Marlene H. Dortch August 24, 2015 Page 2 In further support of this request, Intelsat hereby attaches Exhibits A and B, which contain technical information that demonstrates that the operation of the earth station will be compatible withits electromagnetic environment and will not cause harmful interference into any lawfully operating terrestrial facility, as well as a waiver request. Intelsat also notes that for purposes of the GSAT—18 LEOP mission, it is seeking to operate in the frequencies listed in the request at power levels not to exceed 31.8 dBW. 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—18 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—18 satellite. This, in turn, will result in the provision of a replacement satellite from the 74.0° E.L. orbital location for a currently operational satellite and thereby promotes the public interest. Please direct any questions regarding this STA request to the undersigned at (703) 559—6949. es 4h Respectfully submitted, Cynthia J. Grady Regulatory Counsel Intelsat Corporation cc: Paul Blais
