摘要
基于蜂窝的定位与基于卫星的定位都是当今无线定位的研究热点。在分析了独立采用基站TDOA定位和同步卫星TDOA定位技术的优缺点基础之上,提出了蜂窝网无线定位辅以同步卫星TDOA的定位方法,给出了各自的TDOA定位的算法,并分别对TDOA定位性能进行了仿真和分析,表明这种定位方法弥补了独立的蜂窝网无线定位和同步卫星定位系统的不足,可以适应不同环境的定位需要。
The location based on wireless cellular network and satellites are all hotspot technology today. In this paper, after analysis of the merit and shortage of TDOA location based on base station or synchronous satellite,the method of TDOA location of wireless cellular network assisted synchronous satellite is presented. The algorithms for location are respectively given, and each location performance is simulated and analyzed. A conclusion is made that the shortage of wireless location independently based on cellular network and synchronous satellite is made up by this location method , which can adapt to different situations in application.
