基于DGPS的车辆定位系统研究

DGPS Based Automatic Vehicle Location System

讨论了一种基于DGPS的车辆定位系统。描述了定位系统的硬件结构 ,结合GPS的误差模型建立了卡尔曼滤波方程 ,使得定位系统具有整体最优估计效果。跑车实验表明 ,所讨论的方法是行之有效的。

A DGPS based Automatic Vehicle Location (AVL) system is discussed.The hardware construction is described,and the Kalman Filter equation is conducted based on the error model of GPS,which can make the AVL system to work in the optimal mode.The method has been proven to be effected in the practice.
