Design and Implementation of Avionic Autonomous Management System for Deep Space Exploration

Autonomous management technology is an important means to ensure the long-term safety and autonomous operation of deep space exploration spacecraft on orbit. The development of autonomous management technology of some typical foreign spacecrafts is firstly summarized in this paper. And secondly, based on analyzing the needs of autonomous management of deep space exploration spacecraft, the design and management strategy of autonomous management system are proposed. Then the system architecture and engineering implementation of corresponding avionic autonomous management system are given, by taking the trial new-generation manned spaceship as an example. The results of the on-orbit operation demonstrated that the spaceship could realize functions of autonomous orbit control, autonomous management of flight state, autonomous health management of critical equipment, autonomous disposal of modules separation and autonomous control of reentry in case of non-ground intervention, which ensured the safety of spaceship to the greatest extent and effectively improved its reliability of autonomous operation.
