The research project "The Geodynamics at the North Mediterranean" was prepared on the basis of the geodynamics research in the framework of the CERGOP II project. Results obtained so far are presented, as well the project, in which the Italy, Slovenia and Croatia participate in the united project about the Geodynamics of the Adriatic Plate at the juncture of the European and African Plates.

One of the main objectives of the second phase of the Project CERGOP-2 (Central Europe Regional Geodynamics Project) is to continue studies on geotectonic regions of Central Europe. A special study group CSG.% "Geotectonic analysis of the region of Central Europe" chaired by the authors was established in 1999 to coordinate the research of particular sub-groups. There are 7 sub-groups: 1. Monitoring of recent crustal movements in Eastern Alps and the North and Eastern Adriatic with GPS (chaired by Italy). 2. Three dimensional plate in Romania (co-chaired by Germany and Romania) 3. Integration of present geodynamic investigations in the Pannonian Basin (chaired by Hungary) 4. International geodynmics of the Tatra Mountains (co-chaired by Poland and Slovakia) 6. Geodynamics of Northern Carpathians (chaired by Ukraine) 7. Geodynamics of the Balkan Penisula (chaired by Bulgaria). Programme and updated plan of work within the second phase of the project CERGOP-2 for 2002-2004, methods of coordination and expected results are given in the paper.

CERGOP-2 is the second phase of a long range European project focusing on the GPS monitoring measurements of ongoing tectonic deformation processes in Central Europe. In the year 2000 processing and analysis of the CEGRN`99 GPS observing campaign was carried out. Most of the CERGOP study groups were active and presenting interesting results. Significant intraplate velocities have been mapped and geophysical interpretations were given for selected areas. Discussions have been continuede on the future trend, which way CERGOP should evolve.

Project CERGOP is the main project realised in international cooperation of the European countries in the frame of the scientific programme of seventeen countries assembled in the CEI (Central European Initiative) WG Science and Technology Section C "Geodesy". The objective of the first phase of the international geodynamic project CERGOP (Central Europe Regional Geodynamics Project) was the establishment and maintenance of the Central European GPS Reference Network (CEGRN). The CEGRN consists now of more than 60 sites located on the territory of 14 countries The CEGRN reference network of the first phase of the project concluded in 1998 consisting of 31 reference points was performed with an accuracy of 2-4 mm in horizontal coordinates and 4-8 mm in vertical coordinates. Since 1994 four epoch five-day monitoring satellite GPS CEGRN campaigns of the first phase of the Project have been carried out in yearly intervals (in 1994, 1995, 1996, 1997); in 1999 and in 2001 two next campaigns of the second phase of the Project were organised and successfully performed. The results of periodic positioning of reference network points enabled us to determine the 3D geotectonic velocity vectors covering the Central European Region.

The development of the space measurement techniques in geodesy makes possible to study more effectively phenomena of global scale, especially the continental plate movements. The paper describes methods of extracting velocities of periodic GPS stations. The method can be divided into two groups. First, obtains velocities of free sulutions of long periods of observations, and second, out of adjustment with reference points with given a priori sigmas. The velocity vectors of the Eurasian plate has been determined by use of the CERGOP`94,95,96,97 and EXTENDED SAGET'98 observation campaigns. Then they were compared to the vectors calculated from NUVEL-1A global model. The results of adjustment with given a priori sigmas are quite coherent tu the ones obtained by model. The free solution results are not consistent with the model values. The reason may be that they are not related to the global plate movement, but to the local stations motion.

CERGOP-2 is the second phase of a long range European project focusing on the monitoring measurements of ongoing tectonic deformation processes in Central Europe. In 1999 on initial observing campaign was carried out on the newly defined CEGRN, the Central Europe GPS Geodynamic Reference Network in 13 countries. The maintenance of the Central European Terrestrial Reference Frame (CETRF) will provide a reliable 3 dimensional intraplate tectonic velosity field covering the Central European Region. The network of permanent GPS stations within CERGOP will emerge as an integrated multipurpose GPS network contributing to geophysical, environmental, meteorological studies and different real time applications in Central Europe.

CERGOP is a long range European project focusing on fhe monitoring measurements of ongoing tectonic deformation processes in Central Europe. In 1994-98 CEGRN, the Central Europe GPS Geodynamic Reference Network was established and monitored with high precision GPS measurements on 31 sites in 11 countries. In the following years we intend to extend and partly densify this network, while keeping to strict design rules. The main objectives of CERGOP 2 are (i) the maintenance of the Central European Terrestrial Reference Frame (CETRF), (ii) provide a reliable 3 dimensional tectonic velocity field covering the Central European Region and integrate this into hierarchically higher level (i. e. global) tectonic models, (iii) geophysical interpretations, (iv) extension of the Central European Regional Geodynamic Network to include new, tectonically relevant sites in the area of study, (v) support local area geodynamic research, environmental studies, seismic hazard assessments, meteorology etc. in the Central European Region based upon the high accurasy space geodetic measurements, carried out on an integrated geodynamic network, The CEGRN. Two new developments should be pointed out since the EGS meeting in the Hague. One is the new approach to the CEGRN GPS permanent stations - which may be developed to a multipurpose and interdisciplinary sensor array. The other is an initiative to unify the ational high precision GPS networks in Central Europe, which were developed before or ndcr CERGOP, having at least one order of magnitude higher spatial density than CEGRN.

In the seventies, seismological studies in Slovenia were complemented by geodetic measurements. The measuring instruments, measuring methods and data-processing algorihms employed have enabled conclusions on the stability or nonstability of a specific area in a relative short time periods. Geodetic networks have been set up along tectonic faults and are located in the most interesting parts of Slovene territory. Changes in the positions of network points are determined on the basis of terrestrial measurements performed in selected time intervals. Recently, these standard measurements have been joined and complemented by GPS measurements. The great further development of this activities were stimulated specially the cooperation in CERGOP I. This contribution presents the development of geodetic measurements of tectonic movements in Slovenia from 1977 to the present. Extremely precise measurements, which frequently do no receive sufficient (financial) support, are able to confirm the stability or nonstability of an observed area and complement seismological (geological) hypotheses and theories.
