基于Google Map的GPS和GSM定位关键技术研究

Research on Key Technologies of GPS and GSM Locating Based on the Google Map

本文介绍了在Android移动终端上GoogleMap的加载方法及基于Android和GoogleMap API在GSM和GPS两种不同方式下的定位技术.此技术实现了移动终端自动接收附近的GSM信息和GPS信号从而获取移动终端的经纬度,也可以通过输入来获取经纬度信息,把得到的经纬度信息写入GoogleMap程序中从而实现在谷歌地图上的定位.技术的关键是通过java编程语言在GoogleMap API中获取在两种不同方式下的经纬度信息.应用结果表明,两种方式利弊互补、相互结合使定位技术应用更加灵活,对定位跟踪系统和物流监控系统等有积极的作用.

This article describes a method to load GoogleMap on mobile terminal of Android, and introduces positio- ning technologies based on Android and GoogleMap API in two different ways of GSM and GPS. This technology en- ables a mobile terminal to automatically receive information from GSM and GPS signals near it so as to obtain the latitude and longitude. Latitude and longitude information can also be retrieved by written to achieve positioning on Google maps. The key technique is to obtain the latitude and longitude information through java programming lan- guage in two different ways in GoogleMap API. Application results show that the advantages and disadvantages of two ways are complementary, combined positioning technology application is more flexible, and it also have a posi- tive effect on positioning tracking systems and logistics monitoring systems.
