THE RELATIVE VELOCITIES ESTIMATION OF THE TECTONIC MOVEMENTS ON THE AREA OF POLISH SUDETY MTS. AND ITS FORELAND

Abstract

Since 1996 on the frame of GEOSUD and GEOSUD II pro­jects, the area of Sudety Mts. and Fore-Sudetic Block (GEOSUD network) is investigated by different geodetic techniques. Seven GPS measuring campaigns (1996-2002) of local geodynamic net­work GEOSUD gave the opportunity to estimate velocities of GPS points. Connection of epoch GESUD network solutions including observations, coordinates and velocities of the EPN permanent sta­tions made possible to determine of absolute ITRF2000 velocities for all pints. The methodology of relative (intraplate) velocities estimation using APKIM2000 and NNR-NUVEL-lA plate kine­matic models of GEOSUD network points and preliminary results were presented and discussed.
