ABSTRACT:
A system for controlling the orbit of a satellite by operating a plurality of thrusters is disclosed. In the system, an actual attitude of the satellite is sensed, an evaluation is set up on the basis of the sensed attitude and compared with a threshold which is adequately changing, and the ON-OFF condition of the firing of the thrusters is based on the relationship between the evaluation value and the threshold.
