摘　　要：多站时差定位系统一般需要通过高频定向通信方式进行信息传输,由于定向通信天线的波束极窄,在实际使用中各站之间往往难以建立无线通信联系。根据各站部署位置的坐标数据,利用其相对空间几何关系,求出了各站通信天线相互指向的准确方位角和俯仰角,大大提高了多站时差定位系统的通信天线对准速度,保证了其定位作用的正常发挥。Directional high frequency communication is commonly used to convey data in the location system using time difference among multi-station. Because of the narrow beam width of the communication antennas, it is usually very hard to link every two stations. Based on the geometrical relations between the stations, the exact elevation and azimuth of every communication antenna is obtained using the geographical coordinate. By making use of these angular values, the directions of communication antennas are correctly set up and the location system performs normally.
