[Abstract]:The location and navigation function of mobile terminal is the core content of mobile interconnection. In military and civilian fields, positioning and navigation services have been put forward higher requirements. But at present, no navigation satellite system can independently meet the indoor and outdoor environment seamless positioning requirements. Therefore, the positioning and navigation system will change from a single signal to a multi-mode signal fusion navigation mode. According to the above analysis and the actual needs, this paper plans to research and implement the mobile positioning and navigation system which integrates Beidou and GPS and wireless signal location function. In the outdoor environment by GPS and Beidou system dual-mode accurate positioning in the indoor environment according to the wireless signal location the mobile terminal multi-mode seamless positioning. The contents of this paper are as follows: 1) the existing positioning technology and positioning system are studied, and the working principle of wireless positioning technology and hybrid positioning technology are studied. 2) the platform architecture of the terminal part of the system is constructed, and the GYM multi-mode satellite receiving module is selected according to the actual demand of the Samsung S5E4412 development board. The software platform adopts Android operating system. 3) analyzing the whole flow of location data from hardware receiving module to electronic map display and reporting service platform, designing and realizing the multi-mode seamless positioning mode, and choosing the localization mode independently; 4) Research and integration of Apache MINA communication architecture and Java EE open source architecture based on Spring Struts hibernate. Implementation of high concurrent request processing capacity of TCP server, and high compatibility of WEB server. 5) the communication process between terminal and location service platform is studied to realize secure and efficient data communication. The innovation of this system lies in the realization of the multi-satellite receiving mode of mobile equipment, which gets rid of the excessive dependence of positioning terminal on GPS system, and solves the problem of low reliability of positioning terminal equipment relying solely on GPS system. At the same time, the multi-mode hybrid positioning mode is used to improve the positioning accuracy. The system realizes the wireless signal positioning in the indoor environment, enables the user to obtain the positioning and navigation service at any time and any location, and meets the higher requirements of the positioning and navigation service. This system can be used to locate navigation and realize terminal position monitoring and secure communication through positioning service platform, which has good application value.
