%X Analyzing the stability of reference points is a key problem in deformation analysis. The reason is that the instability of these points results in the erroneous interpretation of the deformation process. In this paper, the stability of points in a vertical network has been analyzed, using the given methods of congruency and minimum-making the first norm. Comparison of the obtained results proves that the two methods do not provide a unique solution for the problem. Considering the obtained contrary results and the need for the estimation of the absolute displacements of the network points, a new method has been developed. Using the mentioned method, which is based on the reformulation of the corresponding observation equations, makes possible to compute the absolute displacements of the network points with respect to a reference measurement epoch.
