The diagnosis of unknown satellite anomaly by using space weather data

It has been reported that during the period of high solar activity cycle 22 around the years 1989 and 1990 there were 464 cases of satellite anomaly. but this number dropped to 271 cases during the solar cycle 23. This analysis took several low earth orbit (LEO) satellites as an example which experienced anomaly during the years 2000-2009. This analysis gives information that there are 10 cases of anomaly thought to be caused by proton (P) and electron (E) simultaneously, 2 cases caused by proton, 3 cases caused by the electron and 6 cases caused by other sources (unknown anomaly). This research tries to analyze the causes of anomaly for these six satellites by using proton and electron particle data distributed along satellite trajectory provided by NOAA satellite and geomagnetic activity data represented by Kp and Dst indices. The results of this analysis provide information that the attitude control system (ACS) on the satellite sub system suffers more damage than other instruments. Anomalies on Fuse (1), Fuse (2) and Monitor - E satellites are probably caused by the influence of increased plasma by the time geomagnetic storms happened. Other anomalies on Kirari, Obrview 3 and HST satellites require further analysis because space weather data doesn't show the close correlation between satellite anomaly events and space weather phenomena such as proton and electron impacts on satellite and plasma enhancement through geomagnetic storm.
