摘　　要：以高速公路车辆监测为例,提出了以北斗差分定位技术为核心,实现车辆厘米级实时定位,结合地理信息系统(GIS)、嵌入式系统及网络等技术建立基于北斗的车辆精确定位监测系统。论文利用双频相位观测值的宽巷组合,采用LAMBDA方法快速固定整周模糊度,通过实验表明,该种方法在车辆精确定位中切实有效。Taking an example of highway traffic monitoring,this paper puts forward a vehicle monitoring system,which is based on the Beidou differential positioning technology.The system realize a cm-level real-time location,it combined with the geographic information system （GIS）and embedded system and network technology to establish a accurate location based on Beidou.This paper using wide lane combination double-frequency phase observation value and LAMBDA ambiguity search quickly fixed the integer ambiguity,experiments show that this method is practical and effective in precise positioning.
