(‘SES Americom"), by its attomneys, hereby provides the report required pursuantto the above—referenced Commission authorization, granted September 16, 2005. Specifically, paragraph 6 of the terms and conditions of the authorization requires that SES Americom provide a written statement identifying satellites that will be located at or near the assigned orbital Jocation ofAMC—21 and describing the measures that will be taken to prevent in— orbit collisions. AMC—21 is a Ku—band expansion satellite that is assigned to 125° W.L. and is requized to be launched and operational by September 16, 2010. PanAmSat currently operates Galaxy 12 and is authorized to operate Galaxy 14 at the nominal 125° W.L. location.‘ SES Americom is not aware of any other FCC— or non—FCC— Hicensed spacecraft that are operational or planned to be deployed at or near 125° W.L. whose station—keeping volume would overlap with that of AMC—21. SES Americom will coordinate with PanAmSat regarding station— keeping matters to ensure that the collocated spacecraft can operate without collision. Station—keeping approaches that could be used include the Inclination— 1 SES Americom understands that PanAmSat has de—orbited the SBS—4 spacecraft that was previously assigned to the nominal 125° W.L. orbital location.

The Massachusetts Institute of Technology‘s Lincoln Laboratories advises SES Americom regarding government spacecraft and other objects that approach or might enter an assigned station—keeping volume of SES Americom‘s operational spacecraft. SES Americom coordinates either through Lincoln Labs or the other Commercial Satellite Operator with respect to any actions that are appropriate at those times to avoid any risk of collision.
