25. Influence Analysis of the High-Energy Electrons on Geosynchronous Orbit Satellite

In order to clarify why there is abnormal appearance of GEO satellite, and improve the reliability of the satellite, this paper introduces the mechanism of the earth’s radiation belts and energetic particles first, which leads to the fact that GEO satellite is in bad space environment. Then based on the monthly space environment data from the Chinese academy of sciences for Space Environment Prediction Center (SEPC) and National Satellite Meteorological Center (NSMC), combined with the fault data from one GEO satellite, by statistics and analysis, it comes to the conclusion that the high energy electrons in the earth’s radiation belts is a major cause of GEO satellite fault. Next according to the theoretical analysis, the conventional prediction and special prediction, the prediction technology of high energy electrons is discussed. In order to enhance the accuracy of satellite fault prediction and the ability of space situation awareness, reduce the risk of long-term management and the personnel pressure, it’s necessary to strengthen the high energy electrons real-time prediction, which is in the space environment of GEO satellite.
