航天器受空间环境影响而中断运行任务是普遍存在的问题,迫切需要寻找合适的预警方法为在轨处置提供支持。利用综合因子层次分析计算方法,将空间环境特征数据、敏感参数及异常发生情况等信息进行整合,分析航天器遥测参数与空间环境特征数据的相关性,计算出空间环境变化导致特定航天器在轨异常的预警数值,为航天器运行管理工作提供依据。
The interruption of operational mission of spacecraft affected by the space environment is a common problem and there is an urgent need to find a suitable early warning method to support on-orbit disposal. Using the comprehensive factor analysis method, the spatial environment characteristic data, the sensitive parameters and the occurrence of anomalies are integrated to analyze the relativity between the spacecraft telemetry parameters and the spatial environment characteristic data, and the spatial variation of space environment is calculated to make the specific spacecraft on orbit Abnormal early warning value for spacecraft operation and management to provide the basis.
