Problems solved by technology

In addition, satellite fault handling has long exit time, short entry time, and long ground processing cycle, which is easy to delay fault processing operations
It can be seen that manual processing of satellite on-orbit faults involves many processes, involves a wide range of areas, and has a long cycle. Therefore, there is an ur

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...

Abstract

The application relates to a satellite on-orbit autonomous fault handling scheme, including step 1) of judging a type of a satellite on-orbit operation fault; and step 2) of performing fault handlingaccording to the type of the fault.

Description

technical field [0001] This application relates to the management software solution for the autonomous operation of satellites in orbit, that is, to propose corresponding technical solutions for autonomous processing of possible faults at different levels of satellites in orbit. This solution can improve the efficiency of on-orbit satellite stand-alone or system failure handling, reduce satellite failure losses, and greatly reduce the rescue cost of ground personnel. Background technique [0002] With the application of industrial-grade devices in aerospace systems, the functions of satellite electronics are becoming more and more complex, and the frequency of satellite in-orbit failures is getting higher and higher. Most of the faults that occur on the satellite in orbit are processed and restored by the instructions of the ground designers after analysis. [0003] The on-orbit operation of satellites is generally monitored and maintained by the ground measurement and cont...
