The processing of GNSS observation by non-classical error theory of measurements

The main goal of our research is to show the need to use modern methods of processing GNSS observations time series by non-classical error theory of measurements (NETM), which is characterized by large sample sizes n > 500. The errors of high-precision observations, for the most part, cannot be represented by the classical law of Gaussian distribution. With the increase in sample size, the empirical error distribution will increasingly deviate from the classical Gaussian error theory of measurements (CETM).

Study of dynamics of horizontal crustal movements in Europe according to GNSS observation (2000–2010)

The main aim of this work is the study of dynamics of crustal movements in Europe for the period from 2000 to 2010. Absolute and regional annual vectors of velocity of displacement of permanent stations are estimated and schematic maps of annual rate of displacement vectors are created, conditional crustal blocks (CCB) which stable kinematics of horizontal displacements of permanent stations are selected. Average annual velocities and directions of movement of these blocks are estimated. These results will be further used to study the crustal deformation in surveying region.

About migration of the extreme values of velocities of the crust dilatation in Europe

GNSS has become common practice in determining movements and deformations of the earth crust in the global and regional scale. The results of observations at 147 permanent GNSS-stations located in Europe have been used to calculate the parameters of crust deformation. Using the Delaunay triangulation, our study region was divided into a network of triangles. Calculated velocity of the dilatation are belonging to the centers of the elementary triangle which was divided our study region. Schemes of the dilatations distribution in Europe from 2000 to 2010 have been created.
