Payload: ARABSAT 4A
Eurostar E2000+ platform
Separated mass: approx. 3,341 kg (7,366 lbs)
Launch Vehicle: Proton M/Breeze M
Weight at liftoff: 691,272 kg (1.5 million
lbs), including payload
Height: 61 m (200 ft)
Launch Time: 2:10 a.m. March 1 Baikonur
20:10 Feb. 28 GMT
3:10 p.m. Feb. 28 EST
Launch Site: Baikonur Cosmodrome, Kazakhstan
Launch Pad 39
End User: ARABSAT, Riyadh, Saudi Arabia
Satellite Manufacturer: EADS Astrium, Toulouse, France
Launch Vehicle Khrunichev State Research and Production
Manufacturer: Space Center, Moscow
Launch Services International Launch Services (ILS),
Provider: McLean, Va.
Satellite Use: 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 Apogee: 35,786 km (22,236 miles)
at Separation: Perigee: 3,150 km (1,957 miles)
Inclination: 14.2 degrees
Spacecraft Separation: Approximately 4 hours after liftoff
