Deformation of geodetic network based on GPS data in the Baltic region

For investigating the horizontal deformations of geodetic networks the data of GPS measurements of the epochs about 1992 and 2003 were used. To avoid the impact of the discrepancy of the systems of coordinates upon the parameters of the deformations, the method of tensor analysis was applied using...
