发布时间：2018-08-31 07:43
【摘要】：依据当前"5GEO+6IGSO+3MEO"星座配置下的北斗卫星导航系统(BDS),结合民航非精密进近(NPA)的应用需求,提出适合BDS定位、导航和授时(PNT)服务层的性能评估指标体系及关系模型,给出BDS关键PNT性能指标的评估方法。通过首都国际机场BDS实测数据的整理分析,对精度、完好性、连续性以及可用性等PNT性能指标进行了定量评估。
[Abstract]:According to the current "5GEO 6IGSO 3MEO" constellation configuration of Beidou satellite navigation system (BDS),) combined with the application demand of civil aviation non-precision approaching (NPA), the performance evaluation index system and relation model of BDS positioning, navigation and timing (PNT) service layer are put forward. The evaluation method of key PNT performance index of BDS is given. Based on the analysis of the measured data of BDS at Capital International Airport, the performance indexes of PNT, such as accuracy, completeness, continuity and availability, are evaluated quantitatively.
