| 摘 要： | 针对单一导航定位手段的精度和使用范围在车辆导航定位技术中的局限性,提出了采用GPS、DR与电子地图组合导航的方案.经过对GPS/DR/电子地图组合导航定位方法地深入研究,表明GPS/DR电子地图组合导航是一种较为理想的车辆导航方式,它克服了GPS信号受阻时定位间断或失效的缺点,又避免了航位推算定位误差随时间的积累,提高了导航定位的精度并扩展了使用范围.

| Abstract: | In view of single navigation precision and the scope of application of means which has its limitation in technology in navigation, we put forward the scheme to coordinate with the GPS, DR and electronic map. Through further investigation of the navigation of the GPS/DR /electronic map which show that the making up of the GPS/DR/electronic map is the ideal method of navigation. It overcame the shortcomings such as disconnection and invalidity and also avoid the accumulation of navigation location calculation orientation errors with the time passing .It has improved the precision of the localization of navigating and expanded the scope of application. |
