Launch Services
Provider:                International Launch Services, McLean, Va.

Satellite Use:           High-power communications satellite operating
                         at C- and Ku-band to expand digital
                         television broadcasting, data transmission
                         and telecommunications services to North
                         America

Satellite Statistics:    -- 1st delivery-in-orbit launch for Alcatel
                             by ILS
                         -- 8th Alcatel satellite launched by ILS
                         -- 5th ILS launch for AMERICOM
                         -- 16th in SES AMERICOM constellation
                         -- Orbital location: 85 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 parking orbit of 180 km (112
                         miles), inclined at 51.6 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 36,000 km (22,300
                         miles).

Target Orbit
at Separation:           Apogee: 35,786 km
                         Perigee: 6,661 km
                         Inclination: 17.54 degrees

Spacecraft Separation:   Approximately 8 hours, 55 minutes after
                         liftoff
