摘要
指出GPS控制网的平差计算是以GPS基线向量在WGS84坐标系中的三维坐标差(dX,dY,dZ)为原始观测值的平差,探讨了产生误差的环节和原因,以及控制误差的思路,保证了数据的真实准确。
It points out that the adjustment calculation of the GPS control network taking the three-dimensional coordinate differences（dX,dY,dZ） of the GPS basic line vector in the WGS84 coordinate system as adjustment of raw measurement value,discusses links and causes of resulting to error,as well as thinking of controlling error,and ensures reality and accuracy of data.
