Alsat-1 First Algerian Low Earth Orbit Observation Microsatellite in Orbit

The attitude determination and control system Alsat-1 uses a Y momentum and Z reaction wheels, 3-axis magnetorquer rods and a single butane gas thruster for orbital maintenance. The magnetorquer rods do momentum maintenance and notation damping for Y/Z wheels, vibration damping and yaw phase control. This paper describes the attitude determination and control system on Alsat-l first Algerian micro satellite in orbit. The attitude determination sensor required, is a magnetometer and sun sensor and the actuator required is a Y/Z wheels and magnetorquer coil. In orbit results is presented
