Dortch Secretary Federal Communications Commission 445 12th Street, S.W. Washington, D.C. 20554 Re: SES Americom, Inc. Fleet Management Notification for AMC-3 Call Sign S2162, File No. SAT-MOD-20161025-00102 Dear Ms. Dortch: SES Americom, Inc. (“SES”), by its attorney and pursuant to Section 1.65 of the Commission’s rules, 47 C.F.R. § 1.65, hereby updates the record in the above-referenced fleet management notification to provide additional information regarding the C-band polarization of the AMC-3 satellite following its relocation to 72° W.L. Specifically, the AMC-3 C-band polarization remains in the same configuration as when the satellite operated at 67° W.L. – SES has not switched the polarization to match that of AMC-6 when it was operating at 72° W.L. As a result, the AMC-3 even-numbered C-band transponders in the downlink continue to use vertical polarization, and the odd-numbered transponders in the downlink use horizontal polarization. SES informed Star One, which operates the satellites with C-band payloads that are closest to 72° W.L. on either side, of its intention to retain the current AMC-3 polarization for operations at 72° W.L. In its response to SES, Star One indicated that it did not have concerns regarding this matter. SES requests that the Commission update its records to reflect this information regarding the AMC-3 operational characteristics at 72° W.L. Please contact the undersigned if you have any questions. Respectfully submitted, /s/ Karis A. Hastings Karis A. Hastings Counsel for SES Americom, Inc. karis@satcomlaw.com cc: Stephen Duall, IB Satellite Division Kathyrn Medley, IB Satellite Division
