【摘要】 随着移动定位技术、无线通讯网络、地理信息系统、移动互联技术的飞速发展,基于位置服务(Location-Based Services ,LBS)的应用也得到快速发展。LBS是以位置服务为核心,通过通信网络获取移动终端用户的位置信息(经纬度坐标),在地理信息系统的支持下,为用户提供包括信息追踪、导航、移动黄页等多种位置服务的一种新型业务,其核心技术就是移动定位技术。而随着移动定位技术的发展成熟,位置服务业务也进入了面向市场高度发展的阶段。本文主要介绍位置服务的各种相关技术和移动定位技术的主要手段,然后就目前的市场实际提出了一个简单的定位补充方法即:运用里程表结合陀螺仪和精确的GIS系统来实现车辆(移动台)的自身定位,并对其基本应用和发展提出了自己的看法。本文首先介绍了位置服务系统的特点、典型结构和相关技术,包括移动定位技术、移动互联网访问技术、地理信息系统等;然后对其核心技术-移动定位技术做了深入的分析阐述,就其分类、目前已有的几种定位方式一一做了说明;随后根据移动定位系统的设计要求,提出了一个简单的定位系统:里程表结合陀螺仪和GIS系统(OGG),并对其基本原理和实际应用做了阐述。更多还原

【Abstract】 With the rapid development of wireless mobile position technology, communication network, geographical information system and mobile internet technology, the application of location based services(LBS) are booming. LBS is a new type of business service which provides position service including information tracking, navigating, and moving Yellow Page by obtaining the position information(the longitude and latitude coordinate) of the mobile end client through the communication network and by the supporting of geographical information system, mobile position technology are the key. With the development and maturation of the mobile position technology, the location based service are going into the high-development phase which faced the market. In this thesis, the pivotal technology of LBS and main instrument of MP are described, and an easy means of MP is reinforced: use odometer combined with gyroscope and GIS to achieve the position of cars, and put my view on it’s appliance and development forward.Firstly, the features, typical architecture and the pivotal technologies of LBS are introduced, which including mobile position technology, mobile internet accessing technology and geographical information system. Then the pivotal technology- MP technology is deeply discussed. In the following, we put forward a simple MP system based the design demand of MP system-OGG system(Odometer-Gyroscope GIS System).更多还原
