摘    要:北斗卫星导航系统(BDS)已向亚太区域提供正式服务并开始建设北斗全球系统。为了评估验证北斗系统在高速移动条件下的实时差分定位精度,本文设计了动车组实时高精度定位系统并建设了高速铁路试验段。实测结果表明,高速移动条件下动车组列车实时定位的水平垂直轨道方向精度优于1 m,具备区分清楚动车组列车所处轨道的能力,一定程度上能满足铁路行业定位应用的迫切需求。

关 键 词:北斗卫星导航系统  动车组列车  高精度  实时差分  高速移动

Abstract:BeiDou navigation satellite system has possessed formal services for the Asia-Pacific region and begun the construction of BeiDou’s global satellite navigation system.For evaluating the real-time differential positioning accuracy of BDS under the high-speed moving conditions, a real-time high-precision positioning system is designed for EMU trains and a high-speed railway test section is constructed.The field testing results show that the real-time positioning accuracy in vertical track direction on level can be better than 1m under the condition of EMU train high speed moving which indicates that the system has the ability to clearly distinguish the track of the EMU train.To a certain extent, the system can meet some urgent needs of the positioning applications in railway industry.
Keywords:BDS  high-speed EMU  high-precision  real-time difference  high-speed moving
