Example Embodiment
[0022] The technical solutions of the present application will be clearly and completely described below in conjunction with the drawings and the embodiments of the present application.
[0023] There are three main types of satellite failures in orbit. One is the failure of the mission input layer, that is, the ground mission planning error, which causes the satellite to perform the wrong mission; the second is the satellite system layer failure, that is, the ground injection data error, which causes the satellite system to enter the safe mode; the third is the single layer failure, that is Affected by the orbital space environment, a single satellite fails and cannot work normally. In view of the above three failures, the failure mechanism is analyzed, and an on-orbit autonomous troubleshooting plan is proposed.
[0024] Specifically, when the mission data packet is injected, if the mission data packet validity telemetry shows invalid, it is judged as a mission input layer failu...
