Embodiment 1
[0044] figure 2 A flow 20 of an embodiment of a low-orbit satellite-based fault diagnosis and handling method according to the present application is shown. like figure 2 As shown, a low-orbit satellite-based fault diagnosis and treatment method, which is executed in the satellite, specifically includes the following steps:
[0045] S200. Acquire performance parameters used to characterize the operation of the satellite.
[0046]In a specific embodiment, the satellite is composed of seven subsystems, namely the structural mechanism subsystem, the thermal control subsystem, the power supply subsystem, the star affairs management subsystem, the measurement and control subsystem, the attitude control subsystem and the payload subsystem . Each subsystem is composed of different components, and the performance parameters used to characterize the operation of the subsystem are also different. For example, the power subsystem is composed of solar battery wings, battery packs, a...
