| 摘 要： | 介绍车载导航定位系统的组成,比较几种导航方法的优缺点,得出几种较为合理、精度较高的组合定位方法.GPS卫星信号所包含的定位信息有其特定的格式,通过编写程序将其中所需的定位信息提取出来,并利用七参数转换方法将GPS定位系统应用的WGS-84坐标系转换成国家大地坐标系.通过车载导航试验实例分析表明,利用最短距离投影法得到的电子地图精度较高.

| Abstract: | It presents the constitution of vehicle navigation and positioning system by comparing the advantages and disadvantages of several navigation methods.Several reasonable and higher accuracy combination positioning methods are obtained.Positioning information contained in GPS satellite signal has specific format which can be extracted through programing.The WGS-84 coordinate system in GPS positioning system is transformed into the national coordinate system with seven parameters conversion method.Through the test examples,a conclusion is made that electronic map obtained by use of the shortest distance projection method has higher precision. |
