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.
