摘要
首先分析了GPS平差数据,介绍了GPS测量的基线改平的方法 ;然后着重分析了高差误差对改平边长的影响,提出了控制网长度变形检查的新方法。
This article described the theory and technology of GPS baseline reduction based on GPS adjustment data at first.And then it introduced the influence of altitude error on the reduction.At last it proposed a practical method to detect the distortion of side length.
