Abstract :
The authors describe the overall studies on SPOT1 and SPOT2 satellites, in order to assess the validity of upset rate prediction. Upset anomalies detected on OBC (On Board Computer) memory are dealt with. Heavy ion test results obtained during a recent campaign on the IPN Tandem accelerator are presented. The calculations done are summarized, pointing out the best choice of input parameters to achieve a realistic prediction. The goal is to improve the quality of event rate estimation, through a systematic collection of on-orbit anomalies related to charged particles
