Please Note: Target orbit information updated as of 6 April at 12:30 p.m. EDT.

Payload: Anik F3, Eurostar E3000 platform
Separated Mass: Approx. 4,640 kg (10,229 lbs)

Launch Vehicle: Proton M/Breeze M
Weight at Liftoff: 691,272 kg (1.5 million lbs), including payload
Height: 57.2 m (186.6 ft)

Launch Time: 04:54 April 10 Baikonur, 22:54 April 9 GMT, 18:54 April 9 EDT
Launch Site: Baikonur Cosmodrome, Kazakhstan; Launch Pad 39

End User: Telesat Canada, Ottawa, Ontario

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 Use: Multipurpose communications satellite with payloads
in Ku-, C- and Ka-band. The Ku- and C-bands will carry a wide range of
broadcasting, telecommunications, business and Internet-based services
throughout North America. The small Ka-band payload will supplement
services now carried on Anik F2.

Satellite Statistics:
– 32 active Ku-band transponders
– 24 active C-band transponders
– 2 active channels at Ka-band
– Orbital location: 118.7 degrees West longitude
– Anticipated 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 reference, or 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: 5,500 km (3,418 miles); Inclination: 11 degrees

Spacecraft Separation: Approximately 9 hours, 11 minutes after liftoff
