摘要
本文研究了在无法到达区无地面控制网的目标定位方法,研制了GPS激光测距动态定位系统装备;开展了陆上、水面试验,分析了系统在静态/动态条件下的定位精度;验证了该系统在水上等特殊动态测量模式下的可用性,结果表明该系统可以快速对无法到达地区的目标点完成三维定位,外符合精度优于1m;系统操作方便,结构可靠,性能稳定。
The method of positioning in some unreachable areas without the terrestrial control network was studied and GPS and Laser Ranging Dynamic Positioning System was developed in the paper. In order to verify the availability of this system on the water and in special dynamic survey and so on, the experiments of this system were developed on the land and water and the positioning accuracy was analyzed in the static and dynamic conditions. The result showed that it could implement the three dimensions positioning of un- reachable objects quickly with outside fitting accuracy of less than 1 mete ; the system was proved of easy operation, structural reliabili- ty, and steady performance.
