Satellite Use:    
QuetzSat-1, part of the 45+ satellite fleet of SES, will be located at the 77 degree west orbital location at which the Mexican Government has granted the DTH frequency rights to QuetzSat S. de R.L. de C.V., a Mexican-controlled company comprised of SES and Mexican investors. The spacecraft will provide coverage over Mexico, North America and Central America. The spacecraft is fully contracted to EchoStar Corporation and will be used in part by Dish Mexico, an EchoStar joint venture, for DTH services in Mexico and to a subsidiary of DISH Network for use in connection with its U.S. DTH business.

Satellite Statistics:    
__ 32 Ku-band transponders
__ Orbital location: 77 degrees west
__ Anticipated service life:  15 years

Mission Profile:    
The Proton M launch vehicle, utilizing a 5-burn Breeze M mission design, will lift off from Pad 39 at Baikonur Cosmodrome, Kazakhstan, with the QuetzSat-1 satellite on board. The first three stages of the Proton will use a standard ascent profile to place the orbital unit (Breeze M upper stage and the QuetzSat-1 satellite) 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 a circular parking orbit, then to an intermediate orbit, followed by a transfer orbit, and finally to a geosynchronous transfer orbit. Separation of the QuetzSat-1 satellite is scheduled to occur approximately 9 hours, 13 minutes after liftoff.

Target Orbit at Separation:
Apogee: 35,786 km (22,236 miles)
Perigee:  5,983 km (3,718 miles)
Inclination: 18.6 degrees

SES-3 Spacecraft Separation:        
Approximately 9 hours, 13 minutes after liftoff
