基于GPS激光主动式定位系统定位方法研究

A Research on Positioning Method of Laser Active Positioning System Based on GPS

介绍了GPS激光主动式定位系统的硬件组成及功能,分析了该方法定位的基本原理,并对试验结果进行了分析,验证该方法的可行性及定位精度。利用系统在不同的流动站对目标利用系统同轴望远镜进行照准,发射激光获取不同流动站的距离,利用数字罗盘获取激光仪的姿态,GPS_OEM获得流动站点的GPS坐标。利用空间距离交会原理解算目标的3维坐标,为不易到达的测区提供技术方法。

This paper introduces function and hardware components of the laser active GPS positioning system,and analyzes the basic principles of the method and the results of the experiment,verifies the feasibility of the method and positioning accuracy.Coaxial telescope of the target utilization system is calibrated by means of moving the system among different mobile station,distance between mobile stations is obtained by laser emission,the attitude of the laser equipment is obtained using digital compass,and GPS coordination of mobile station is obtained through GPS_OEM.The three dimensional coordinate of the target is resolved using spatial distance intersection which provides technical method for areas difficult to reach.
