快速静态GPS与数字水准仪相结合确定像控点的实践

Practice on Combining Fast Static GPS with Digital Leveling Equipment to Determine Ground Control Points

本文应用快速静态GPS与数字水准仪相结合测定像片控制点，对快速GPS控制网的精度和GPS水准测量的高程拟合精度分别进行了分析探讨。经内业解析空三加密验证，该方法不仅能够满足大比例尺地形图内业加密及成图的需要，而且较传统联测方法可提高工作效率5倍以上。

In this paper, a method to combine the fast static GPS with digital levehng is used to measure the coordinates of the ground control points. And then, the paper analyzes the precision of fast GPS control network and elevation fitting precision of GPS leveling. It is proved by aerial triangulation that this method can meet the requirements of the office densification work and large scale topographic mapping, and can improve work efficiency by five times for the conventional surveying.
