Abstract: This work is devoted to the question of differentiation of the rotational movements of the European continent’s earth crust relative to the Euler pole based on the results of the GNSS observations. Based on the analysis of scientific publications it is determined that with the help of paleotectonic data differentiation of tectonic plates can be performed, that is to allocate separate blocks for whole tectonic plates, which have different rotating characteristics. The methodology and algorithm for conducting tectonic differentiation according to the results of GNSS observations, namely on the basis of vectors of the absolute displacement of GNSS stations are developed. According to the algorithm the division of the European tectonic plates into two blocks with different rotational parameters is obtained. According to certain parameters model values of the velocity vectors of displacement of GNSS stations and their accuracy assessment is calculated. The movement of one block in relation to another as immovable is investigated. The corresponding maps and diagrams to illustrate the obtained results are constructed.
