ABSTRACT:
The spacecraft system has automatic fault detection and autonomous reconfiguration of redundant hardware and software to correct that fault without ground station intervention. The spacecraft has redundant processors, sensors, control systems and buses. When a unit is believed to have failed as detected by the satellite processor unit, it switches to a backup unit. If the symptom persists after the unit is switched, the processor unit switches to a different bus. If the fault still exists, a new processor unit is switched in and the entire checking and switching repeats.
