AMOS-1 [2] [3] is a commercial communication satellite. It was the first Israeli communications satellite. The satellite was positioned at 4 deg west longitude in the geo-stationary orbit.
Its development is based on experience from Ofeq reconnaissance satellites in association with DASA and Alcatel Espace. It was launched at May 16, 1996 from Kourou in French Guiana. It is in use for home TV services (DTH/DBS by "Yes" company in Israel and by HBO and others in Europe. Spacecom succeeded quickly to fill all transmission abilities of AMOS-1 and accumulated additional requests. Therefore Spacecom decided to broaden its activity and initiated AMOS 2 creation, which is today in its full ownership.
AMOS-1 carries nine Ku-band transponders.
Weighing 970 kg at launch, AMOS-1 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-1 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 1380 W power, backed up by 24 A·h Ni-Cd batteries.
After its launch into Geo-synchronous transfer orbit by Ariane 4, AMOS-1 it 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.
