Prognostics and Health Management of Monitoring Receiver

Monitoring receiver is one of the core equipment of satellite navigation system, its maintenance play an important role in continuous and stable operation of the satellite navigation system. This paper presents the concept of PHM health assessment and forecast of monitoring receiver, gives the concept of monitoring receiver health parameter, and analyzes monitoring receiver health assessment method which used the number of health parameters deviation and deviation probability. Then this paper summarizes parameter acquisition, data processing, evaluation, diagnosis and trend forecast, and has a good reference to improve operation maintenance skills to the further explore the satellite navigation system failure forecast and evaluation technology
