Abstract:
In this paper, about 10 years' dare of the spacecraft anomaly caused by space environment for the satellites (including SCATHA, TDRS-1, GPS and GOES) running near or on geosynchronic orbits are analyzed. For these anomaly, their yearly, monthly, hourly in local bine as well as different anomaly type distribution characters are studied respectively. The result shows that diversified space environment causes various types of spacecraft anomaly due to its different effects on spacecraft. (1) No general character exists for effects of long-term and/or short-term solar activities on spacecraft anomaly. (2) From a view of long-term, SEUs are mainly caused by heavy ions from galactic cosmic ray and solar proton event is not important to SEUs. (3) The study and prediction about space environment are very important and necessary to analysis, recognition, prediction and shielding for spacecraft anomaly.
