SES-3 is a commercial communications satellite from SES World Skies .
mission
It was put into geostationary orbit by International Launch Services (ILS) on July 15, 2011 at 23:16 UTC with a Proton-M launcher from launch site 200/39 in Baikonur (together with KazSat 2 ) .
payload
The three-axis stabilized satellite with 24 Ku-band - and 24 C-band - transponders equipped and two 2.3 m and large antennas to provide 103 degrees West from the US with various video, voice and data services on the position. From mid-2012, SES 3 will be the successor to AMC 1 , which has been in space since September 8, 1996 . It was built on the basis of the STAR-2.4E satellite bus by Orbital Sciences Corporation (OSC) and has a planned service life of 15 years. It is the third satellite in a new series of spacecraft that the manufacturer from Dulles in the US state of Virginia built for SES, the 29th satellite in the total SES World Skies fleet, and the 40th satellite for the parent company SES. The energy supply is provided by two solar cell arms, which together can generate around 5 kW of electrical power. The structure of the satellite corresponds to its predecessors SES-1 and SES-2 , whereby SES-2 is still equipped with a Commercially Hosted InfraRed Payload (CHIRP) called the US Air Force payload.
