摘要
根据工程勘测的需要,应用大地测量学及GPS网平差理论,结合实例,探讨运用边长尺度比来有效消除GPS网平差中高斯投影及高程归化变形的计算方法。
According to the demand of engineering surveying , With the theory of geodesy and the method of gps network adjust , This paper discusses how to minimize the scale error of gauss projection and datum plane reduction by changing the side scale when we adjust the engineering gps network.
