摘　　要：电厂GPS控制测量中不可避免地存在着距离长度变形,根据工程测量的需要,介绍了处理投影变形的理论依据,对限制长度投影变形的方案进行了探讨,并结合工程实际提出了解决方案。同时提出运用重心坐标原理同时对两个厂区进行投影变形的处理方法,保证两厂区GPS控制网的内部精度。Length deformation is inevitable in GPS control surveying. In order to meet the need of engineering surveying, this paper introduced the program of constraining the projection deformation. At the same time based on the principle of barycentric coordinates, the paper proposed the processing methods of projection deformation between two different plant area to keep the internal precision of GPS control net.
