Satellite Use: AMC-23 is a high-power hybrid C/Ku-band satellite that will
serve local, transcontinental and transoceanic customers throughout the
Pacific Region, including North America, Asia, Australia, New Zealand,
Indonesia and the islands of the South Pacific.
Satellite Statistics:
2nd Spacebus 4000 to be launched by ILS

20 Ku-band transponders

18 C-band transponders

Orbital location: 172 degrees East longitude

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 support or reference orbit of 173 km (107 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 36,000 km (22,300 miles).
Target Orbit at Separation:
Apogee: 35,786 km (22,236 miles)
Perigee: 6,400 km (3,977 miles)
Inclination: 18.3?
Spacecraft Separation: Approximately 9 hours, 20 minutes after liftoff
ILS Mission Statistics:
4th ILS Proton mission this year

11th launch by ILS vehicle for SES AMERICOM fleet

35th ILS mission on Proton

317th Proton mission overall
