June 3, 2019 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 KA258 Dear Ms. Dortch: Intelsat License LLC (“Intelsat”) herein requests an expedited grant of Special Temporary Authority (“STA”)1 for 30 days, commencing June 20, 2019, to use its Hagerstown, Maryland Ku-band earth station (call sign KA258) to provide ground segment telemetry, tracking, and command (“TT&C”) services to the T16 satellite (call sign S3039).2 Specifically, Intelsat seeks to provide launch and early orbit phase (“LEOP”) services; TT&C during in-orbit testing (“IOT”) at 134.75° W.L.;3 TT&C during the satellite’s drift from its IOT location to its final location of 100.85° W.L.; and backup TT&C on- station at 100.85° W.L. The launch is currently scheduled for June 20, 2019 and the LEOP, IOT, and drift are expected to take approximately 45 days. Backup TT&C services at 100.85° W.L. will be provided indefinitely and Intelsat will be filing for authority to provide this service on a permanent basis. The proposed operations will be performed using the following frequencies: 17789.0 MHz and 17791.0 MHz (RHCP) in the uplink; and 12697.0 MHz and 12698.0 MHz (RHCP) in the downlink. The proposed operations will be coordinated with all operators of satellites that use the same 1 Intelsat has filed its STA request, an FCC Form 159, a $210.00 filing fee, and this supporting letter electronically via the International Bureau’s Filing System (“IBFS”). 2 See Satellite Policy Branch Information, Actions Taken, Report No. SAT-01381, SAT-RPL- 20180913-00071 (Mar. 29, 2019) (Public Notice); see also Satellite Policy Branch Information, Space Station Application Accepted for Filing, Report No. SAT-01392, SAT-MOD-20190508-00036 (May 24, 2019) (Public Notice) (seeking modification to change the assigned orbital location of T16 to 100.85° W.L.) 3 See Satellite Policy Branch Information, Actions Taken, Report No. SAT-01394, SAT-STA- 20190508-00037 (May 31, 2019) (Public Notice).

Ms. Marlene H. Dortch June 3, 2019 Page 2 frequency bands and are in the drift path.4 All operators of potentially affected satellites 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 T16 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. The proposed TT&C operations at 100.85° W.L. will be consistent with the coordination agreements for the nominal 100.85° W.L. orbital location entered into by DIRECTV Enterprises, LLC – the licensee of T16. In the unlikely event that harmful interference occurs, Intelsat will take all necessary steps to eliminate the interference. In further support of this request, Intelsat hereby attaches Exhibit A, which contains 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. 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 T16 LEOP mission, Airbus will serve as the mission manager. Airbus 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 Airbus. 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. 4 Airbus, the mission manager of the T16 mission, will handle the coordination.

Ms. Marlene H. Dortch June 3, 2019 Page 3 Grant of this STA request will allow Intelsat to help safely launch, test, deploy, and station-keep T16. This, in turn, will help support direct-to-home services from the 100.85° W.L. orbital 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.
