基于GPS汽车导航接收系统的设计

目录

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(Global Positioning System，简称GPS)技术得到越来越多的应用。车载定位导航系统(Vehicle Location and Navigation System，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。

Abstract

In recent years, along with high accuracy, low price, real-time, safereliable localization survey and time service method appearance,global positioning system (Global Positioning System, is called GPS)the technology to obtain more and more many applications. Theautomobile is in the modern civilized society will relate the closestone kind of transportation vehicle with each person, will apply theglobal positioning system to the vehicles navigation becomes one ofglobal satellite positioning system application biggest potentialmarkets. The vehicle carries the positioning and navigation system (VehicleLocation and Navigation System, the abbreviation (VLNS), in brief, isuses the nowadays universal popular global positioning system (GPS),carries on the geography localization to the chassis in the position,and unifies with geographic information system GIS, coordinates thecity electron map and the main transportation road electron map,provides the real-time driving navigation information for the driverthe system.

The present paper first introduced the global positioning systemgeneral principle, the positioning system composition and thecharacteristic, and have carried on the detailed analysis to the GPSlocalization principle and the system error; Carried the localizationnavigation software and hardware system to the vehicle to do in detailelaborated that, designed and has analyzed the signal receive modulewith emphasis, formed the error to the receiving process in to carryon the analysis and the improvement; A this design important functionis uses the electronic map the road net, designs the reasonabletopology, and uses the Dijkstra algorithm to design one kind of mostshort-path to seek the superior method.
