當衛星發生異常時，將對衛星運作和儀器觀測有很大的影響，可能造成衛星的運作中斷或儀器的資料錯誤。然而造成衛星異常的情況很多種，所以我們需要先了解異常的發生原因，才能提早預測異常或找出因應的解決辦法。從福衛二號以及福衛三號的衛星異常事件中，我們依照不同的異常原因做分類，將非太空天氣影響的事件去除後，對剩下的可能受太空天氣影響事件做分析。在分析的過程中，我們使用地球磁場以及太陽風資料來分析這些異常事件，並且利用這些太空資料來分析出衛星發生異常時，主要太空環境情形以及影響衛星發生異常的主要條件。;When an anomaly occurs in a satellite, it can have an influence on the operation to the satellite and the instruments on board, possibly resulting in a disruption the satellite operation or some inaccuracy in the data obtained. Therefore, we need to well understand the causes of anomalies so that we can develop an application to predict them earlier and mitigate the impacts. In this study, we classify the satellite anomalies reported from the Formosat-2 (FS2) and Formosat-3/Cosmic (FS3) satellite for different types of anomalies. After we removed the non-space weather events, we analyze the remaining events in combination with geomagnetic fields and solar wind data. using these space data to analyze the main space environmental conditions when the satellite anomalies occurred.
