High-Reliability Autonomous Management Systems for Spacecraft updates on research on three levels of self-management, including: 1) Autonomous health management of spacecraft that covers how spacecraft can monitor their own state and autonomously detect, isolate and recover from faults; 2) Autonomous mission management of spacecraft where the spacecraft can directly receive the mission, formulate a reasonable plan according to the current state and working environment of the spacecraft, and convert the mission into a specific sequence of instructions; 3) Spacecraft autonomous data management where the spacecraft processes a large amount of raw data and extracts useful information, and autonomously executes or changes flights. The autonomous management of spacecraft uses modern control technologies such as artificial intelligence to establish a remote intelligent body on the spacecraft so that the spacecraft can complete its flight tasks by itself. Its goal is to accurately perceive its own state and external environment without relying on external information injection and control or rely on external control as little as possible.
