SES AWORLD SKIES Daniel C.H. Mah Regulatory Counsel (202) 478—7137 August 20, 2010 VIA E—MAIL Paul Blais Chief, Systems Analysis Branch Satellite Division, International Bureau Federal Communications Commission 445 12"" Street S.W. Washington, D.C. 20455 Dear Mr. Blais, Re: File No. SES-MOD-20100615-OOW, Call Sign WB81 SES Americom, Inc. (doing business as "SES WORLD SKIES") hereby amends its pending application (File No. SES—MOD—20100615—00702) as follows: = The modifications proposed in the pending application for Antenna 1 should in fact be for Antenna 2 on the subject license (Call Sign WB81). While SES WORLD SKIES submitted a coordination report for Antenna 1, the coordinated parameters in that report would cover the proposed operation of Antenna 2, which is located nearby and has very similar characteristics. Antenna 2 is slightly larger than Antenna 1 and has a lower transmit gain. It is also situated about 1 second away from Antenna 2. a For the 3MOQF3W analog emission, the maximum EIRP per carrier shouldbe 83.79 dBWaand th i RP density per carrier should be 55.05 dBW/4 kHz. i € designator band using both linear and circular polarizations. These power levels are consistent with 47 C.F.R. § 25.212 and less than the power levels in the coordination report. = ,For the 36M0G7W digital emission, the maximum EIRP per carrier should be 83.79 dBW and the maximum EIRP density per carrier should be 44.25 dBW/4 V~__ kHz. SES WORLD SKIES is seeking authority to operate this emission designator across the entire 5925—6425 MHz band. These power levels are consistent with 47 C.F.R. § 25.212 and less than the power levels in the coordination report.

Paul Blais Page 2 of 2 a The off—axis performance of the Antenna 2 has previously been certified to comply with 47 C.F.R. § 25.209. This combined with the reduced power levels proposed above ensures consistency with the off—axis power limits in 47 C.F.R. § 25.218. Given the extent of the corrections, SES is filing an amendment to the pending modification application to reflect these changes. A copy of this letter will be associated with the amendment. Please contact me if you have any questions. Yours sincerely, Daniel C.H. Mah Regulatory Counsel SES Americom, Inc. ce: Frank Peace, FCC
