航天器遥测数据可信度分析与研究

Analysis and research on the reliability of spacecraft′s telemetry data

航天器遥测数据由于误码的原因,具有不准确性。为了解决故障诊断时遥测数据导致推理结果的不准确性,提出在遥测数据上加可信度后再发送给推理机。本文研究分析了航天器缓变遥测参数值的特性并给出其可信度定义,依据其特性提出了计算缓变遥测数据的可信度算法,并进行了结果验证。

Because of miscode, the spacecraft＇s telemetry data doesn＇t have accuracy. In order to solve diagnosis result not have the accuracy when carries on the fault diagnosise, so proposed adds the reliability to telemetry data then sent to inference machine. The article analyses characteristics of slow telemetry parameter＇s data and gives the definition of its reliability. Proposing arithmetic of calculating slow telemetry data reliability based on its characteristics , giving the verification of result.
