The technique applied in the processing and analysis of measurements on three geodynamic polygons is considered. This method was used in research [4–6], which systematized and analyzed all the cycles of measurements at these polygons: North Caucasus, Baikal (three constructs) and the North Sakhalin. Before processing the results’ data verification of zero statistical hypothesis for presence of any significant network deformations had been made. If the hypothesis were rejected, the analysis would be carried out for displacement of points. The results were presented and described in view of seismic events associated with time measurements on the polygons and the tectonic structure of the studied area.
