Analysis of the observation of particle detector inside ‘CBERS-1’ satellite under solar quiet conditions

Human’s technical systems are greatly influenced by space environment with the in- crease of space activities. It was reported that 70% of 1589 US’ satellite anomalies during 1971―1986 and 40% Chinese geosynchronous satellite anomalies were related to space environment. One of the important factors which causes spacecraft anomalies is the en- ergetic particles[1,2], which mainly come from radiation belts. Several decades after the discovery of the radiation belts by Van Allen in 1958, the…
