Abstract
The work mode of remote sensing satellite in orbit is flexible and diverse, the working state and parameters of the satellite under different working modes are very different, which brings some difficulties to the autonomous health management of remote sensing satellite. In order to associate satellite health management with working mode, a health management method based on finite state machine (FSM) is proposed. Taking the working modes as the state, the switching operation of each mode (such as switching on and off of equipment, etc.) as the state transfer condition, the autonomous health management disposal measures under different states as the execution action, the refined autonomous health management model under different working modes is established. The actual flight verification of a remote sensing satellite shows that the autonomous health management design is reasonable and feasible, and the finite state machine modeling method is universal and reusable.
