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...

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 the method of finite elements. A geodetic network consists of 19 triangles; 15 geodetic ground benchmarks observed by GPS method were used. The horizontal deformations of geodetic network in the territory of the Baltic Sea region were calculated. The maximum relative strain in the territory of the Baltic Sea region varies between +0,03×10–6 and +0,58×10–6 and is positive within the whole territory; the minimum relative strain varies between –0,93×10–6 and +0,03×10–6; and the dilatation varies between –0,35×10–6 and +0,16×10–6.
