摘　　要：在分析遥感卫星自主健康管理需求和目标的基础上,对自主健康管理进行分级,提出高分三号(GF-3)卫星自主健康管理系统架构,设计可重配置的遥测在轨实时监测与量化管理系统,实现了标准化遥测监视表设计、可量化故障事件包设计、可量化统计事件包设计、故障和统计事件包自主生成条件、曲线比对功能等共性关键技术。GF-3卫星在轨运行结果表明:卫星能够在非地面干预的情况下自主对整星健康状态进行实时监测,并在故障发生时实施自主诊断、隔离和恢复,最大限度地保证卫星安全,有效提高卫星在轨自主运行的可靠性。An autonomous health management classification is made based on the analysis of re-quirement for remote sensing satellite.The architecture of GF-3 satellite autonomous health management is proposed,and satellite telemetry real-time monitoring and quantitative manage-ment system on-orbit is designed.The key technologies are described including standardization table of telemetry monitoring,quantitative fault event packet,quantitative statistic event pack-et,and curve comparison function.The results of GF-3 satellite on-orbit operation show that the satellite telemetry data are monitored in real-time,and the fault detection,isolation and re-covery strategy are triggered in case abnormal telemetry characteristic occurs,therefore autono-mous health management is useful to assure the safety of satellite, and to improve the reliability of spacecraft autonomy.
