Satellite south Atlantic anomaly area safety protection autonomous control method and system

The invention discloses a satellite south Atlantic anomaly area safety protection autonomous control method and system. The method comprises the following steps: analyzing the characteristic information of the south Atlantic anomaly area and establishing a load autonomous safety protection judgment criterion; calculating the state value S of the south Atlantic anomaly area by the numerical controlsubsystem according to the load autonomous safety protection criterion; and determining the high energy payload, the medium energy payload, the low energy payload and whether the integrated controller enters the anomaly area according to the calculated state value S of the south Atlantic anomaly area. The accurate identification of the satellite passing through the south Atlantic anomaly area canbe realized. 本发明公开了一种卫星南大西洋异常区安全保护自主控制方法和系统，该方法包括：对南大西洋异常区的特征信息进行解析，建立载荷自主安全保护判定准则；由数管分系统根据载荷自主安全保护判定准则，计算得到南大西洋异常区状态值S；根据计算得到的南大西洋异常区状态值S，确定高能有效载荷、中能有效载荷、低能有效载荷、以及搭载综合控制器是否进入异常区。本发明实现了对卫星通过南大西洋异常区的准确识别。
