PURPOSE:To prevent a fault, by executing a limit check processing routine by a CPU, and automatically switching a main component which can be a problem in a turning satellite, to a holding redundancy system. CONSTITUTION:When a ground command (a) is sent, it is decoded by a satellite telemetry command system 1, and a driving signal (b) is sent to a switching relay 3 of the inside of an electric power source system 2. Subsequently, a common electric power source (c) is switched to a main system 5 or a redundancy system 6 of an attitude sensor 4 being an attitude control system component, and said signal is applied as a signal (d) or (c). An attitude sensor to which an electric current is supplied, for instance, the main system 5 sends a signal (e) which is varied in accordance with an attitude of a satellite, to an attitude control electronic device 7. This attitude control electronic device 7 processes a signal by a CPU8 of the inside, generates a driving signal (l) to a satellite actuator 10 by a signal converting amplifier 9, and controls the attitude. |
