Launch Pad 24
Launch Customer: SES AMERICOM, Princeton, N.J.
Part of SES GLOBAL family of companies
Satellite Manufacturer: Alcatel Space, Cannes, France
Manufacturer: Khrunichev State Research and Production
Space Center, Moscow
Provider: International Launch Services (ILS), McLean,
Satellite Use: Formerly called Worldsat-2, the AMC-12 is a
high-power C-band satellite with three
regional beams: North America, South America
and Europe/Africa. It will support a wide
range of communications applications.
Satellite Statistics: -- 1st Spacebus 4000 to be launched
-- 3 regional beams
-- 72 C-band transponders
-- Orbital location: 37.5 degrees West
-- Anticipated service life of 16 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 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).
at Separation: Apogee: 35,786 km (22,236 miles)
Perigee: 6,400 km (3,977 miles)
Inclination: 18.3 degrees
Spacecraft Separation: Approximately 9 hours, 20 minutes after
ILS Mission Statistics: -- 1st ILS Proton mission this year
-- 5th ILS launch for SES AMERICOM in
-- 32nd ILS mission on Proton
