Satellite Use:    
SES-3, the 45th satellite in the SES fleet, is part of a total fleet of more than 40 satellites of parent company SES. The satellite is expected to replace AMC-1 at 103° West longitude in mid 2012 and provide continuity of service to the enterprise, government and media sectors from the center of the North American arc. SES-3 will be the home of key media companies delivering educational, international and high definition video channels throughout the U.S. The satellite will also be powering mobile communications, private networks and thousands of VSAT terminals for the enterprise community. SES-3 is the third satellite in a new generation of SES WORLD SKIES satellites bearing the “SES” name, joining the existing line of AMC satellites over North America and the NSS satellites covering the rest of the world.

Satellite Statistics: 
__ 24 C-band, 24 Ku-band, 500 MHz Ka-band
__ Orbital location: 103 degrees west
__ Anticipated service life:  15 years

Mission Profile:
The Proton M launch vehicle, utilizing a 6-burn Breeze M mission design, will lift off from Pad 39 at Baikonur Cosmodrome, Kazakhstan, with the SES-3 satellite on board. This a shared launch configuration, where the SES-3 satellite is launched while mated to the top of the KazSat-2 satellite. The first three stages of the Proton will use a standard ascent profile to place the orbital unit (Breeze M upper stage and the SES-3 and KazSat-2 satellites) into a sub-orbital trajectory. From this point in the mission, the Breeze M will perform planned mission maneuvers to advance the orbital unit first to an elliptical parking orbit, then to an intermediate orbit, followed by a transfer orbit, and finally to a geosynchronous transfer orbit. Separation of the SES-3 satellite is scheduled to occur approximately 8 hours, 1 minute after liftoff. An hour later, the Breeze M that will place the KazSat-2 satellite directly into geosynchronous orbit. Separation of the KazSat-2 satellite is scheduled to occur approximately 9 hours, 24 minutes after liftoff.

Target Orbit at Separation:
Apogee: 35,786 km (22,236 miles)
Perigee:  3,690 km (2,293 miles)
Inclination: 24.7 degrees

SES-3 Spacecraft Separation:  
Approximately 8 hours, 01 minute after liftoff
