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 urgent need for independent processing capabilities for satellite faults with clear states.
[0004] For satellite faults, the existing literature has proposed technologies for intelligent fault diagnosis and intelligent fault processing, but the emphasis is on theory, and there is no feasible technical solution for actual engineering

Embodiment Construction

[0022] The technical solutions of the present application will be clearly and completely described below in conjunction with the accompanying drawings and the embodiments of the present application.

[0023] There are three main types of satellite failures in orbit. The first is the failure of the mission input layer, that is, the wrong planning of the ground mission, which causes the satellite to execute the wrong mission; Due to the impact of the orbital space environment, the satellite unit fails and cannot work normally. Aiming at the above three faults, the fault mechanism is analyzed, and an on-orbit autonomous fault handling scheme is proposed.

[0024] Specifically, after the mission data packet is injected, if the validity telemetry of the mission data packet shows that it is invalid, it is judged to be a fault at the mission input layer; when the telemetry of the satellite working mode shows that it has entered "safe mode", it is judged to be a fault at the satellit...

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...
