基于GPS/DR的车载导航设备的改进及算法

Improvement and Algorithm for Vehicle Positioning System with GPS/DR Device

将 GPS 定位航位推算(DR)技术结合起来,可以用于车辆的定位和导航中。但是现有的航位推算设备都需要用角度传感器测量车辆的行驶方向,在实际应用中存在很多不便而且性价比不高。为解决这一问题,通过研究设计了只使用速度传感器就可以进行航位推算的设备,并对设备的工作原理、体系结构和基本算法进行了介绍。通过对模拟实验数据进行分析,证明了这种航位推算方法可以很好地弥补 GPS 导航定位的不足。

A new solution is used to the DR equipment, which is based on speed sensors instead of the traditional inconvenient solution that is based on angle sensors. The operating principle, system architecture and fundamental algorithm are introduced. This method can greatly make up the shortcomings of GPS positioning.
