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。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 1 m 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.
