End User

Arabsat, Riyadh, Saudi Arabia

Satellite Manufacturer

EADS Astrium, Toulouse, France

Launch Vehicle Manufacturer

Khrunichev State Research and Production Space Center, Moscow

Launch Services Provider

International Launch Services (ILS), McLean, Va.

Satellite Uses

Multipurpose communications satellite serving Arab countries and neighboring regions.  A hybrid Ku- and C-band payload will carry direct-to-home, interactive TV and internet broadband services, with additional capacity to accommodate anticipated demand for high-definition TV.

Satellite Statistics

16 active Ku-band transponders

24 active C-band transponders

Orbital location:  26 degrees East longitude

Anticipated service life of 15 years

Mission Profile

The Proton launch vehicle will inject the satellite into geosynchronous transfer orbit, using a four-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:  3,150 km (1,957 miles)

Inclination: 14.2 degrees

Spacecraft Separation

Approximately 4 hours after liftoff
