Analysis on Space Environment from the Anomalies of Geosynchronous Satellites [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2009
While it is well known that space environment can produce spacecraft anomaly, defining space environment effects for each anomalies is difficult. This is caused by the fact that spacecraft anomaly shows various symptoms and reproducing it is impossible ...
