嵌入式GPS轨迹记录仪

Route recorder of GPS position system based on ARM

设计了一种基于嵌入式技术的车载GPS导航系统用以实现对用户行驶路线的记录。本文主要对3个方面的技术进行了研究:一是介绍了GPS技术的原理、特点、系统组成和定位方式;二是介绍了嵌入式车载GPS轨迹记录仪的硬件结构、设计思路和实现方法。三是结合GoogleEarth的3维实景地图实现将使用者所在的位置及行走速度和方向显示并存储记录,并对实验结果进行校正。该嵌入式车载GPS轨迹记录仪实现了对用户运行路线的定位、记录与再现。

A route recorder of GPS position system based on ARM is designed in this paper in order to record the user’s route. Mainly on the following three techniques were studied： first, principles, characteristics and compositions of GPS technology was introduced; Second, the hardware platform based on ARM is presented; Third, the positions, speed and direction of the user are showed and remembered at the same time by using the Google Earth 3-D Virtual Maps, the experimental results are also corrected. It has been proved that the system in this paper can record the route .
