The possible effect of the reductions to the measured distances between the points in a geodynamic geodetic network on the reliability of the subsequently calculated deformations has been analyzed. Experimental investigations on the basis of doubly measured spatial chords from the real network and their analogues in UTM-projection have been planned and implemented. Reduction adjustments have been indisputably found to lead to distortion of the deformation model.

Two models have been proposed – static and kinematic – for modelling of the contemporary vertical crustal movements. Herein are demonstrated: the mathematical mechanism, the experimental investigations, the analysis of the results and some graphical representations. Based on the modelling, the relevant conclusions have been drawn.
