Abstract
A method of on-board dynamic health management for spacecraft TT&C transponder is proposed. The on-board working state of TT&C transponder is a process of dynamic change in a certain and limited range. The CTU belonging to the OBDH subsystem collects the working state of the TT&C transponder in real time, and judges whether the operation of TT&C transponder is normal by judging whether the current state is consistent with the expected state. The CTU software designed the state machine of health state detection of TT&C transponder, established a health management data model, completed the autonomous health detection of TT&C transponder and the autonomous reset operation, and realized the on-board abnormal removal of TT&C transponder.
