The research of spacecraft on-orbit health management technology

In order to avoid causing serious aftermath by faults of on-orbit spacecraft, need for timely faults diagnosis and faults prediction to take effective measures to minimize security risks and the impact on the mission. The research of spacecraft on-orbit health management technology is carried out in this paper, the system components of spacecraft on-orbit health management system and a solution to fault diagnosis expert system based on neural network and fault trees analysis are discussed. Aiming at the power subsystem of on-orbit spacecraft. Demonstrate and validate of health management and detection system to verify the feasibility of health management programs is also carried out in this paper, and the purpose to enhance the reliability and increase the life span of on-orbit spacecraft is achieved.
