摘　　要：本文阐述了一种基于GPS(全球定位系统)与SMS(短信息服务)的自助汽车定位终端的设计原理及其实际应用。该终端的最大特点是不需“控制中心”,而“控制中心”是其他GPS系统的关键组成部分。该终端由CPU处理器模块、SMS模块、GPS模块、位置存储器等部分组成,用户可以随心所欲的将汽车的位置信息与行驶速度、方位等通过短信方式显示在手机上。本文重点介绍了SMS模块、GPS模块与位置存储器的嵌入式开发,以及如何应用这三个部分实现位置信息的快速显示。This article discusses the design principles and practical application of a self-help automobile orientation terminal based on GPS and SMS. The typical feature of this terminal is that it can work without a ＂control center＂, which is the key part of other GPS systems. The terminal consists of CPU processor module, SMS module, GPS module and location memorizer. Users can freely display the information about the automobile＇ s location and speed on their mobile phones though short message. This article mainly introduces the imbedded development of SMS module, GPS module and location memorizer, besides, it also deals with the ways of displaying the location information fleetly by these three modules,
