August 28, 2018 Ms. Marlene H. Dortch Secretary Federal Communications Commission 445 12th Street, S.W. Washington, D.C. 20554 Re: Request for Special Temporary Authority Napa, California Earth Station E950307 Intelsat License LLC (“Intelsat”) herein requests a grant of Special Temporary Authority (“STA”) 1 for 30 days, commencing September 25, 2018, to use its Napa, California C-band earth station—call sign E950307—to provide telemetry, tracking, and command (“TT&C”) during in-orbit testing (“IOT”) of Horizons 3e (S2947) at 164.0° E.L and TT&C during the drift of Horizons 3e to its final location of 169.0° E.L. Horizons 3e is expected to be launched on September 18, 2018.2 The IOT and drift are expected to last approximately 3 months. The proposed operations will be performed using the following frequencies and frequency bands: 6421.5-6425.0 MHz, and 5850.0-5853.5 MHz in the uplink (LHCP/V); and 4197.75 MHz, 4198.25 MHz, 4198.75 MHz and 4199.25 MHz in the downlink (LHCP/V). The proposed operations will be coordinated with all operators of satellites that use the same frequency bands and are in the drift path or are potentially affected by these operations at the IOT location. 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 Horizons 3e 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 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 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 permanent orbital location for Horizons 3e will be at 169.0º E.L. See Policy Branch Information; Actions Taken, Report No. SAT-01313, File No. SAT-MOD-20170622-00093 (April 27, 2018) (Public Notice).

Ms. Marlene H. Dortch August 28, 2018 Page 2 transmissions to or from its earth station, Intelsat will take all reasonable steps to eliminate the interference. Grant of this STA request will allow Intelsat to help launch and test the Horizons 3e satellite. This, in turn, will help provide additional capacity to customers at the 169.0º E.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.
