抗差自由网、非自由网平差的回归算法

叙述了在回归方法基础上的控制网平差算法，这种方法可以分解探测值粗差和起算数据粗差的过程，因此可以把控制网看作自由网逐步代入任一坐标系统。文中介绍了一系列作者研究的理论，例如，临时绘定未知数个数的方法，回归平差方法的进一步发展等。这种算法可以应用到传统地面网的平差，地面网与卫星空间网的联合平差，以及变形网的平差，而且已编成软件包ＡＤＪＳＴ。

The Regression Algorithm for Adjustment of Free-networks and Non-free-networks

The algorithm for adjustment of control networks based on regression method is put forward in this paper.The control networks can be regarded as the free networks and substituted into any coordinate systems because the regression algorithm can decompose the probe process of the gross error of measurements and initial data.A series of theory that authors studied ,such as provisionally given number os unknown numbers and that authors studied the regression adjustment method,and so on,are discussed in this paper.These methods of adjustment can be applied to the traditional adjustment of ground networks,simultaneous adjustment of ground networks and satellite spatial networks and adjustment of deformation monitoring networks.The Software package ADJST has been compiled.
