Influence of Space Environment on the Beidou Satellite and Its Countermeasures
2017
Space environment is the main factor that infects the operation and the safe of the satellites. The operation of the satellite components and electronic equipment may be destroyed because of various environmental factors, the performance of devices is decreased and damaged. The safety of the satellite in orbit is threatened. Since the running of the Beidou Navigation Constellation, a large number of satellite anomalies have been caused because of the space environment, the failure of the satellite components have been caused, the service of navigation and the safe of platform has been influenced. Several typical space environment effects and different influences on spacecraft are researched in this paper. The causes of faults which are associated with space environment are studied. The laws of generation of fault are analyzed. The disposal strategies of resolving these faults are presented. It is valuable for the Beidou satellite fault prediction and proposal. Meanwhile, it is helpful for the research department in the later designation.
