摘要
为了克服传统车载导航定位技术的不足,提高定位精度,文中将基于北斗卫星导航系统的主辅站技术应用于车载导航中,主辅站技术有着可靠性高,无需双向数据传输和服务用户无数量限制等优点。理论研究和实践表明,基于主辅站技术的车载导航定位系统,其定位精度可以达到厘米级,实现车道级定位导航,并能在车辆即将越界时提供预警,防止车辆违章,具有一定的实用价值。
In order to overcome the shortages of traditional vehicle navigational technology and to improve positioning accuracy ,a technology based on the MAC （Master-Auxiliary Corrections） technology of BDS is put forward ,which can be used into the vehicle navigation .The advantages of MAC technology include high reliability ,no two-way transmission and infinite users .Theory and practice show that the plane positioning accuracy of vehicle navigational system based on MAC technology will reach centimeter-level ,moreover .It is valuable that the system can remind drivers of not border‐crossing .
