摘要
为克服基于GPS/GSM定位方式存在定位时间长、在城市中定位信号弱、定位精度低等缺点,首先介绍了GPSOne技术的基本原理,然后结合GPSOne技术,提出了一种基于矢量地图的位置服务系统。基于矢量地图的位置服务系统可为用户定制各种随身增值服务,包括自我定位、城市指南、旅游导航、物流系统等。它可以为用户提供快速、准确的位置地图服务。给出了该系统设计和实现的详细过程,并给出了相应的源代码。
The basic principle of GFSOne was introduced.A new position service based on the vector map was pres- ented with combination of the technology of GPSOne,in order to overcome the defaults of long positioning time, weak positioning signal and low positioning accuracy based on the technology of GPS/GSM.Systems can be custom- ized for various accoutrements of value-added services,including self-positioning,city guides,tourist guide and lo- gistics systems.Moreover,the system is able to provide users with fast,a...
