It was originally ordered by SES Americom as a ground spare for AMC-5R, however in April 2008 a decision was made to launch it, and it was named AMC-1R. It was subsequently renamed AMC-4R, and finally SES-1 after SES Americom merged with SES New Skies to form SES World Skies.[1] It was the third World Skies satellite to be launched following the merger, but the first to carry the new SES designation.[2] SES-1 operates in geostationary orbit, and is intended to be located at a longitude of 101 degrees West, where it will replace the AMC-2 and AMC-4 satellites, and be used broadcast high-definition television to very small aperture terminals in the United States.[1] SES-1 was built by Orbital Sciences Corporation, and is based on the Star-2.4 satellite bus. It is equipped with 24 G/H band (IEEE C band), and 24 J band (IEEE {{Ku band}}) transponders, and at launch it had a mass of {{convert|3170|kg}}. It has a design life of fifteen years, however it was launched with enough fuel to operate for at least sixteen if its systems are still functional.[2] The launch of SES-1 was conducted by International Launch Services, using a Proton-M carrier rocket with a Briz-M upper stage.[1] The launch occurred from Site 200/39 at the Baikonur Cosmodrome, at 11:19:00 GMT on 24 April 2010.[3] The launch successfully placed SES-1 into a subsynchronous orbit close to geostationary altitude.[1][4] In May and June 2010, SES-1 was positioned close to 131° West to temporarily provide backup to the AMC-11 satellite in the event that AMC-11 could not continue broadcasting whilst it is moved out of the way of the failed Galaxy 15 satellite, which passed close to it at the end of May.[5] In the end, services provided by AMC-11 were not interrupted.[6] See also{{Portal|Spaceflight}}
