| 摘 要： | 在讨论GPS网起算点变形的基础上,利用其包含长度信息和方位信息的特点,将变动点的坐标值看作包含粗差的已知值,提出利用全组合求差和Huber估计反复迭代来定位粗差,剔除变动大的点,得到纯净的起算点。该方法适用于起算点较多、平均基线较长(大于5 km)的情况。最后,用算例证明了该法的正确性和适用性。

| Abstract: | Based on the fixed initial deforming point,this paper thinks so points as coarse points,and then deletes them by differencing of each other and Huber robust.This method is applied in those networks having longer baselines and more fixed points.Finally,the paper is testified by one example. |
