Abstract :
Satellites in geosynchronous orbit have been experiencing electronic switching anomalies and component failures since the early 1970s. These upsets are believed to be due to encounters with geomagnetic substorm environments. This concept is examined. Background data are used to establish the frequency and intensity of encounters. Analytical models of generic three-axis-stabilized spacecraft are used to predict the charging and demonstrate the mechanism of coupling to the spacecraft electrical system. It is found that environmentally induced discharges can couple into these systems and cause anomalies
