摘　　要：在车辆监控系统中,利用GPS能够全天候、连续、实时地获得高精度的三维位置航向和速度信息.但是,GPS卫星信号在隧道和山谷容易受到遮挡,通过GPS接收机不能获得连续准确的导航信息.为解决此类问题,讨论了利用滤波算法辅助GPS进行定位,弥补了GPS的缺陷.介绍了车辆监控系统的原理和数学模型,给出了基于DSP的车辆监控系统的硬件组成和软件编程,实现了车辆监控的组合方法.GPS has spread widely in various application fields. The three-dimensional and real-time course position and speed information in high precision can be gained in all-weather condition by using GPS technology in a vehicle monitor systems continuously. But satellite signal in GPS is often sheltered from the channels and mountains. In order to solve the problem, it presents an improved filter algorithm to support GPS positioning. The principle and mathematic model of a vehicle monitor system is described. The hardware and software of DSP based on a vehicle monitor system is designed and implemented. The simulation of the filter algorithm is carried out.
