融合多源数据的北斗卫星导航系统健康管理体系

Health Management Technical Structure of Beidou Navigation System Based on Multi-source Data

针对北斗卫星导航系统健康管理过程中数据融合程度有待提高、星上和地面产品研制和试验数据未得到充分利用的现状,文章结合数据驱动健康管理技术发展基础,提出了涵盖星上产品生产过程数据、在轨遥测数据、可靠性试验数据、服务性能监测评估数据的多源数据融合北斗卫星导航系统健康管理体系,研究了北斗卫星导航系统多源数据融合框架,并按照单机级、系统级、星座级多层次阐述了健康管理的内容和流程,可为北斗卫星导航系统的精细化健康管理提供借鉴。

Multi-source data need to be used for improving efficiency in course of operation.With the development of data-based prognosis and health management(PHM)in the industrial fields,a health management technical structure for Beidou navigation constellation system is proposed,data for manufacture,test,on-orbit monitoring,service evaluation is included,and technical process is explained by equipment level,system level and constellation level,respectively.The proposed structure is benefit for Beidou satellite navigation system optimizing health management and technology development in the future.
