摘　　要：以GPS作为室外定位方式、WIFI作为室内定位方式,研究了基于GPS数量的终端自适应定位模式选择及自动切换策略。开发了基于高德地图的服务器程序和Android终端位置定位信息推送软件,实现了实时位置服务信息自动推送。经校园环境下测试,该系统能按照部署测试点进行相关信息的推送服务。实验测试表明,GPS和WIFI定位精度分别可达40m和30m。Taking GPS as an outdoor locating method and WIFI as an indoor locating method, the adaptive locating mode selection and automatic switching strategy based on the number of GPS are studied. The software is developed based on Amap server and Android terminal, to realize the real-time location service information push. In the campus environment, the developed system can be carried out in accordance with the deployment of the test points to push the relevant service information. The experimental tests show that the locating accuracy of GPS and WIFI can reach 40m and 30m respectively.
