AMC-11 , previously GE-11, is a Dutch, previously American geostationary communications satellite which is operated by SES World Skies. It is currently positioned in geostationary orbit at a longitude of 131 degrees West, from where it is used to relay cable television across North America for onward distribution. It broadcasts to Canada, the Caribbean, Mexico and the United States.
AMC-11 was built by Lockheed Martin, and is based on the A2100A satellite bus. It was originally ordered by GE Americom as GE-11, however following the merger of GE Americom and SES, it was redesignated AMC-11 while still under construction. It is equipped with 24 transponders operating in the G and H bands of the NATO frequency spectrum, or the C band of the IEEE spectrum. At launch it had a mass of 2,340 kilograms (5,160 lb), with an expected operational lifespan of around fifteen years.
The launch of AMC-11, which was conducted by International Launch Services, was the penultimate flight and last commercial launch of the Atlas II carrier rocket, which flew in the Atlas IIAS configuration. The launch occurred from Space Launch Complex 36B at the Cape Canaveral Air Force Station, at 22:22 GMT on 19 May 2004. The launch successfully placed AMC-11 into a geosynchronous transfer orbit, from which it raised itself to geostationary orbit by means of a LEROS-1C apogee motor. Its insertion into geosynchronous orbit occurred at 20:00 on 24 May 2004.
