Location Based Services And Mobile Position Technology Research

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).
