Provider: International Launch Services (ILS); McLean, Va.

Satellite Use: MEASAT-3 will provide high-powered C-band coverage over more than 100 countries comprising more than 70 percent of the world's population, and DTH-quality Ku-band coverage to over 160 million TV households in Malaysia, Indonesia and South Asia.

Satellite Statistics:
– 24 C-band transponders
– 24 Ku-band transponders
– Orbital location: 91.5 degrees East longitude
– Contractual service life of 15 years

Mission Profile: The Proton launch vehicle will inject the satellite into geosynchronous transfer orbit, using a five-burn Breeze M mission design. The first three stages of the Proton will use a standard ascent trajectory to place the Breeze M fourth stage, with the satellite, into a suborbital trajectory, from which the Breeze M will place itself and the spacecraft into a circular parking orbit of 173 km (107.5 miles), inclined at 51.5 degrees. Then the satellite will be propelled to its transfer orbit by additional burns of the Breeze M. Following separation from the Breeze M, the spacecraft will perform a series of liquid apogee engine burns to raise perigee, lower inclination and circularize the orbit at the geostationary altitude of 35,786 km (22,236 miles).

Target Orbit
at Separation: Apogee: 35,786 km (22,236 miles); Perigee: 7,360 km (4,573 miles); Inclination: 16.5 degrees

Spacecraft Separation: Approximately 9 hours, 12 minutes after liftoff
