Satellite group on-orbit health assessment method and terminal based on time-varying topological structure

The invention discloses a satellite group on-orbit health assessment method based on a time-varying topological structure and a terminal. The method comprises the following steps: assessing the health state of satellites in a satellite group; performing inter-satellite communication link health assessment; evaluating the performance of the satellite group tasks; and calculating a star group health degree value to judge the health level. The satellite group health state information and the satellite group health degree data are obtained, the degree of influence of faults at all levels on satellite group health can be determined, therefore, a maintenance strategy can be designated in a targeted mode, and the method has the advantages of being objective, comprehensive, high in reliability, high in robustness and the like. 本发明公开了一种基于时变拓扑结构的星群在轨健康评估方法及终端，步骤包括：星群中卫星健康状态评估；星间通信链路健康评估；星群任务效能评估；计算星群健康度数值来判断健康等级。本发明获取星群健康状态信息和星群健康度数据，可确定各级故障对星群健康影响的程度，从而可以有针对性指定维护策略，具有客观全面、可靠性高、鲁棒性强等优势。
