高精度位置服务终端技术与应用

Technology and Application of High-precision Terminal Devices in LBS

国外位置服务系统建设的巨大成功,催生了国内位置服务(Location Based Service,LBS)产业的发展热潮,进而影响了位置服务终端的技术革新。位置服务终端作为用户最直接感受到的服务承载平台,面向不同需求的人群提供愈发精细化的服务。在高精度位置服务终端硬件平台基础上,针对亚米级定位性能和位置服务需求,论述了单频精密单点定位技术、地图技术与位置服务网络,开展终端应用示范活动,验证了其具有提供高精度位置信息以及实时位置服务的能力。

The enormous success of foreign LBS construction promoted the development of domestic LBS and affected the technological innovation of the terminal devices.The terminal devices are bearing platform of the user,for the different needs of people,provide fine service.In view of the sub-meter position and service requirements,the paper discusses the single-frequency Precise Point Positioning technology,map technology and network services based the high-precision terminal devices in LBS. Terminal application activities demonstrate that he high-precision terminal devices in LBS have the ability of providing high precision position information and real-time location services.
