航天器故障状态诊断和上行数据验证方法

Method to Diagnose Fault Status and to Verify Up-link Data of Satellite

基于遥测参数静态阈值的航天器故障状态诊断是目前普遍采用的方法,因缺乏验证平台地面系统难以保证上行数据正确;分析了参数静态阈值法的局限,研究了基于状态动态属性的航天器故障状态诊断方法,提出了通过建立仿真平台验证上行数据方法;方法已用于航天器实际测控,状态动态属性方法使航天器故障状态诊断更加准确,根据提出的上行数据验证方法建立的平台多次检查出了上行数据中的错误,提高了航天器控制的可靠性。

Currently, the method to diagnose fault status of satellite based on static threshold of telemetry parameters of satellite is popularly used. It is difficult to verify up--link data because of lack of relative platform. Here, the limitation of current method is analyzed, a new method to diagnose fault status of satellite based on status dynamic attribute is studied, and the way to verify up--link data using simulation platform is proposed. The new method and proposed way have been used to manage in--orbit satellites. It is shown that the diagnosis result becomes more accurate and the correctness of up--link data is guaranteed by use of the new method and proposed way.
