Abstract: Deep space exploration missions have a critical need for spacecraft's onboard autonomy technologies. Autonomous navigation, autonomous fault diagnosis and system reconfiguration are essential cores, and they are also the premise and guarantee for onboard autonomy. Aiming at the spacecraft with severely limited resources, the reporter proposes autonomous navigation methods based on observability theory and autonomous fault diagnosis and system reconfiguration methods based on diagnosability and reconfigurability theory, taking the quantitative characterization of observation, diagnosis, and reconfiguration capabilities as the innovative breakthrough. It has been successfully applied to China's lunar exploration project and the first Mars exploration, making significant contributions to implementing the safe and reliable onboard autonomy of deep space probes.
