1、毕业设计（论文）基于GPS汽车导航接收系统的设计摘要近年来，随着高精度、低价格、实时、安全可靠的定位测量和授时方法的出现，全球定位系统(GlobalPositioningSystem，简称GPS)技术得到越来越多的应用。车载定位导航系统(VehicleLocationandNavigationSystem，简称(VLNS)，简而言之，就是利用现今普遍流行的全球定位系统(GPS)，对车体所在位置进行地理定位，并与地理信息系统GIS相结合，配合城市电子地图及主要交通公路电子地图，为司机提供实时行车导航信息的系统。本论文
2、首先介绍了全球定位系统的一般原理，定位系统的组成和特点，并对GPS的定位原理和系统的误差进行了详细的分析；对车载定位导航软硬件系统做了详细地阐述，重点设计和分析了信号接收模块，对接收过程中形成的误差进行了分析和改进；本设计的一个重要功能是利用电子地图的道路网，设计出合理的拓扑结构，并采用Dijkstra算法设计出一种最短路径的寻优方法。关键词 GPS定位原理；接收机；误差；最短路径寻优AbstractInrecentyears,alongwithhighaccuracy,lowprice,real-time,saf
