摘　　要：依据到达时间差算法对广域多点定位技术的空中飞机定位原理进行说明。为了在J624航线上规划建设一套广域多点定位系统,根据航路图开展地面台址初选工作,并结合实地勘测选取的天线塔架设、机房分类等信息,提出福建省西部山区复杂地形条件下的选址方案。通过WRAP软件对预选台址的信号覆盖效果进行仿真分析,确定该选址方案满足覆盖需求。Based on Time Difference of Arrival (TDOA) algorithm, WAM technology is studied in theory. In order to plan and build a set of Wide Area Multi-lateration (WAM) system on J624 route, selection of ground stations is carried out by contacting route map. Combining the information of antenna tower erection and machine room classification selected in the field survey, the station selection scheme of WAM system under complex terrain in the western mountainous area of Fujian province is proposed. By using the simulation software of WRAP, the signal coverage effect of pre-selected stations is simulated and analyzed, so as to ensure that the stations scheme meets the coverage requirements.
