Washington, D.C. 20554 Re: Request for Extension of Special Temporary Authority Riverside, California Earth Station EO40125 Dear Ms. Dortch: Intelsat License LLC ("Intelsat") herein requests an additional 30 days of Special Temporary Authority ("STA")‘ previously granted Intelsat to use its Riverside, California C—band earth station—call sign E0O40125—to provide launch and early orbit phase ("LEOP") services for the GSAT—19 satellite." GSAT—19 is now expected to be launched on June 5, 2017. The LEOP period is expected to last approximately 10 days.* The GSAT—19 LEOP operations will be performed at the following frequencies: 6410.896 MHz and 6412.912 MHz in the uplink (RHCP), and 4186.848 MHz and 4190.976 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." 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—19 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. ‘ Intelsat has filed its STA request, an FCC Form 159, a $200.00 filing fee, and this supporting letter electronically via the International Bureau‘s Filing System ("IBFS"). * See Satellite Communications Services Information; Actions Taken, Report No. SES—01950, File No. SES—STA— 20170315—00279 (Apr. 26, 2017) (Public Notice).

Ms. Marlene H. Dortch May 24, 2017 Page 2 In further support of this request, Intelsat incorporates by reference Exhibits A and B, which contain technical information that demonstrates that the operation of the earth station will be compatible with its electromagnetic environment and will not cause harmful interference into any lawfully operating terrestrial facility, as well as a waiver request. In the extremely unlikely event that harmful interference should occur due to transmissions to or fromits earth station, Intelsat will take all reasonable steps to eliminate the interference. Finally, Intelsat clarifies that during the GSAT—19 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 remainin control of the baseband unit, RF equipment, and antenna. Grant of this STA extension request will allow Intelsat to help launch the GSAT—19 satellite and thereby promotes the public interest. Please direct any questions regarding this STA request to the undersigned at (703) 559—6949. Respectfully submitted, Cotou_ Q. :4 Ay Cynthia J.
