Spacecraft System Autonomous Health Management Design

Abstract

In order to ensure the stable operation of spacecraft in orbit, improve continuous working capacity and reduce ground management pressure, this paper proposes a hierarchical and distributed spacecraft health management system architecture design, and proposes a healthy data flow design scheme, health data generation and processing methods, health data sharing mechanisms and health data scheduling methods. For the system health management requirements, the paper put forwards some system health management strategies such as spacecraft system monitoring, payload mission safety, power supply safety, safety mode, system recovery and system reconfiguration, etc.
