AMOS-2 [2] [3]is a commercial communication satellite. The satellite was positioned at 4 deg west longitude in the geo-stationary orbit. it was launched at December 27, 2003 from Baikonur, Kazakhstan and it serves clients in three serice regions: Middle East (including Israel), Europe and eastern coast of USA. Transmission and communication services given by this satellite include: direct distribution of TV and radio translations, TV and radio translations to communication centers, distribution of internet services, data tranmissions to communication networks.
AMOS-2 carries Eleven Ku-band transponders.
Weighing 1370 kg at launch, AMOS-2 incorporated a 400 newton Liquid Apogee Boost Motor (ABM) and Fourteen 10 newton Reaction Control Thrusters for raising the satellite's orbit from Geo-stationary Transfer orbit to its final geo- stationary orbit as well as for its altitude control. It carried 450 kg of propellant (monomethyl hydrazine and MON-3).
AMOS-2 measures 11.5 m in length in its final in-orbit configuration. It is 3-axis body stabilised using Sun and Earth sensors, momentum and reaction wheels. Its solar array generates 1700W power, backed up by 24 A·h Ni-Cd batteries.
After its launch into Geo-synchronous transfer orbit by Soyuz, AMOS-2 was taken to its final geo-stationary orbit by firing the apogee boost motor in phases. After it reached the geo-stationary orbit, its antenna and solar Panels were deployed and the satellite was finally placed in its allocated slot of 4° West longitude.
Amos 1 and Amos 2 are placed in proximity to create common location, which enables to satellite users to increase user abilities without additional antennas.
