July 19, 2016 By eFile Marlene H. Dortch Secretary Federal Communications Commission 445 12th Street, SW Washington, D.C. 20554 Re: Application for Authority to Operate EchoStar 1 as an In-orbit Spare IBFS File Nos. SAT-LOA-20150512-00034 Call Sign S2943 (formerly, S2739) Dear Ms. Dortch: EchoStar Satellite Operating Corporation (“EchoStar”) submits this supplemental letter to clarify that its above-referenced application for operating authority of the EchoStar 1 (Call Sign S2943) satellite seeks a license term of approximately five years, expiring in October 2021, consistent with the satellite’s estimated end of life (“EOL”), and to correct the application’s Schedule S information indicating a 12-year license term. On June 17, 2016, EchoStar 1 commenced inclined orbit operations to extend its mission life. As a result, and based upon the amount of useable propellant remaining as of June 30, 2016, the satellite’s projected EOL is October 2021. This projection takes into account the 300 km. EOL disposal requirement, and is based upon a fuel consumption rate for east-west station-keeping maintenance over the last several years of operations. Please direct any questions regarding this matter to the undersigned. Sincerely, /s/ Jennifer A. Manner Jennifer A. Manner Senior Vice President, Regulatory Affairs cc: Alan Thomas (FCC) EchoStar Satellite Operating Corporation 100 Inverness Terrace East • Englewood, CO 80112 • Tel: 303.706.4000
