June 14, 2017 Ms. Marlene H. Dortch Secretary Federal Communications Commission 445 12th Street, S.W. Washington, D.C. 20554 Re: Request for Special Temporary Authority Hagerstown, Maryland Earth Station KA275 Dear Ms. Dortch: Intelsat License LLC (“Intelsat”) herein requests a grant of Special Temporary Authority (“STA”) 1 for 30 days, commencing June 28, 2017, to use its Hagerstown, Maryland C-band earth station—call sign KA275—to provide launch and early orbit phase (“LEOP”) services for the HS3-IS satellite. HS3-IS is expected to be launched on June 28, 2017.2 The LEOP period is expected to last approximately 30 days. The HS3-IS LEOP operations will be performed at the following frequencies: 5923.5 MHz, 6173.7 MHz, and 6426.0 MHz in the uplink (CP), and 3700.5 MHz, 3701.0 MHz, 4197.5 MHz, and 4198.0 MHz in the downlink (CP). 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 HS3-IS 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 request, Intelsat herewith attaches 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 from its earth station, Intelsat will take all reasonable steps to eliminate the interference. 1 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”). 2 The in-orbit testing location for HS3-IS, which Intelsat understands is licensed by Greece, will be 34.5° E.L. and 39.0° E.L. The spacecraft’s final location is 39.0° E.L. 3 Thales Alenia Space (“Thales”), the manager of the HS3-IS mission, will handle the coordination.

Ms. Marlene H. Dortch June 14, 2017 Page 2 Finally, Intelsat clarifies that during the HS3-IS 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 HS3-IS satellite 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.
