The CERGOP2 project funded by the European Union from 2003 to 2006 under the 5th Framework Programme benefits from repeated measurements of the coordinates of epoch and permanent GPS stations forming the CEGRN network in Central Europe, starting 1994. We report on the results of the systematic processing of the available data up to 2005. The analysis work has yielded the velocities of some 60 sites, covering a variety of Central European tectonic provinces, from the Adria indenter to the Tauern window, the Pannonian basin, the Vrancea Seismic Zone and the Carpathian Mountains. The estimated velocities define kinematical patterns which outline, with varying spatial resolution depending on the station density and history, the present day tectonic flow in Central Europe.The CEGRN data show that the majority of active contraction originating from the Eurasia Nubia plate boundary and the microplate between them is taken up primarily in the Eastern Alps, the Dinarides, and the Pannonian Basin. After removal from the ITRF2000 velocities of a rigid rotation accounting for the mean motion of stable Europe, the residual velocities have random orientations with 0.3 mm/yr scatter. This Iow figure provides an upper estimate for the level of rigidity of the European Platform. A 2.3 mm/yr north-south oriented convergence rate is implied by our data between Adria and the Southern Alps, and a narrow - -60 km wide- contraction zone in the Southern Alps is identified, consistently with earlier results. An eastward extrusion north of the contraction zone corresponds with the extension of the Tauern Window. In the southeastern boundary of the microplate, 4-4.5 mm/yr motion of Adria decreases to -1 mm/yr through the microplate, its boundary, and the Dinarides mountain range towards the southwestern part of the Pannonian Basin. Our data suggest that if the Pannonian Basin is subject to deformation, then it is most likely to be compressional than extensional. We conclude that compression and associated contraction due to the Adria collision with the Alps and the Dinarides is likely to fade away in the Western and Northern Carpathians, where our velocities and strain rates show no significant deformation.

The main objective of CERGOP-2/Environment Work Package was defined in the Project as "Monitoring the CEGRN by regular and systematic GPS measurement, satisfying the strict quality standards set by WP2". The main task in the course of the Project was the organization of the CEGRN epoch observation campaigns. Therefore the activies focused on the preparation and the careful realization of these measurements. Two CEGRN campaigns were carried out- CEGRN03 and CEGRN05 - in the same part of the year (in June) in order to minimize seasonal effects in the measurements. In both cases the CEGRN campaigns were overlanned with national campaigns (e.g. in Hungary the HGRN epoch campaigns) by which the scope and efficiency of data availability were greatly enhanced. An other task was to monitor the status of CEGRN. Due to the project support 25 new sites became part of CEGRN, Serbia as a new CEGRN Consortium member (not included in the Project) joined the campaigns in 2005 the first time.

The project "CERGOP-2, a multipurpose and interdisciplinary sensor array for environmental research in Central Europe" was approved by EU within the 5th Framework Program and started April 1st, 2003. The official and of the project is March 31, 2006. However we applied for a prolongation of another 6 months and we are waiting for a relevant decision of EU. In 17 work packages we extented a high quality GPS network in a region covering about 15 % of Europe. It will be operational for the next decade. Velocity field and strain maps for geodynamical investigations and hazard mitigation, data for climate research and weather forecast, data for real time navigation and a seamless data bank for scientific and public access were established. This report gives a final summary of the project was arranged in Sarajevo, Bosnia Herzegovina ( in November 2005), which included a Governing Board Meeting of the CEGRN Consortium (CCGB). Discussions included site quality issues related to site acceptance for CEGRN - the basic reference network, and an open forum on future potential project initiatives. The ADRIA, the GMES (Global Monitoring for Environment and Security), the GEO (Group on Earth Observation), the GALILEO, WEGENER and TOPO EUROPE topical project areas were identified, where the Consortium could participate/contribute significantly. Candidate coordinators were assigned for each area. We have also to think about the continuation of this project - after its termination end of March 2006 or end of September 2006. Driven by the many natural disaster during the last 2 years people expect that science will strengthen its efforts to find solutions for explaining the influence of the forces leading to crust displacement and to determine the location, magnitude and the "date" of future expected sudden displacements, a task, which may take another century of scientific investigations, if even possible.

The main objective of CERGOP Work Package (WP-3) is defined in the project as "Monitoring the CEGRN by regular and systematic GPS measurement, satisfying the strict quality standards set by WP 2". This reporting period was "between campaigns" and therefore the main activities focused on maintenance and extension/densification of the existing CEGRN. The preparation of the CEGRN`05 epoch campaign is the task of the Hungarian group. We have distributed the circulars for the compaign call in early 2005. The CEGRN`2005 will be carried out in 20-25 June 2005 overlapping with the HGRN`05 epoch campaign. Several other activities were carried out in relation to the project e.g. footprint monitoring and the search for a new permamnent site in Hungary.

The project "CERGOP-2, a multipurpose and interdisciplinary sensor array for environmental research in Central Europe" was approved by EU within the 5th Framework Program and started April 1st, 2003. As a result of 17 work packages we expect for the area of investigation (15 % of Europe) a network set-up operable for the next decade, velocity field and strain maps for geodynamical investigations and hazard mitigation, data for climate research and weather forecast, data for real time navigation and a seamless data bank for scientific and public access. The decision of the CEGRN consortium guarantees the continuation of the project after its end (March 2006). After the kick-off meeting in Graz (May 2003) a first semi-annual meeting was arranged in Warsaw (end of September), which included a steering committee as well as a user meeting of the CEGRN consortium (the institutional framework of the project). Discussions included site identification, data access policy issues and the further extension of CEGRN, the basic reference network. The EGLJ annual meeting in Nice (Gil) has been selected for yearly scientific reporting. On this occasion we will give a summary report of the activities of the first project year.

The HOPP device construction makes the precise documentation of site elevation masks easily possible, by using a rotate able adapter and an embedded digital photo camera with appropriate software. The output is a 360-degree horizontally and 30 deg vertically scaled digital image of the site. HOPP will be used for site quality monitoring in the frame of the CERGOP-2/Environment project and in the Hungarian Geodynamic Reference Network (HGRN).

The project "CERGOP-2, a Multipurpose and Interdisciplinary Sensor Array for Environmental Research in Central Europe" was approved by EU within the 5th Framework Program and has been started recently (Aprii 2003). Based on long years of cooperation during the last decade 14 partners of 13 countries situated in Central Europe will manage 17 work-packages. The project will upgrade and condense the existing network CEGRN during the first year to about 80-100 multi-purpose GNSS stations (permanent and epoch). The epoch stations will be measured during the first and the third project year, local campaigns as well as scientific investigations will be carried out during the whole period. As a result we expect for a considerable area of Europe (15 %): A network set-up operable for the next decade; velocity field and strain maps for future geodynamical investigations and hazard mitigation; data for climate research and weather forecast; data for real time navigation, a seamless data-bank for scientific and public access. The CEGRN Consortium will guarantee the required long-term operation, the "Memorandum of Agreement" was signed September 2001 by all project partners. An update of the consortium's status and its activities is given. The paper further discusses which way the Consortium should interact and evolve in the new project environment.

After many years of informal collaboration 13 institutes from 13 Central European countries decidedto formalize their organization for long term maintenance of CEGRN.The CEGRN Consortium was established on 5th of September 2001 in Budapest by signing a Memorandum of Agreement. The participants recognized the importance of international collaboration in the field of Space Geodesy, Geodynamics and Earth Sciences. There is a need for a coherent, high accuracy and high quality reference network in Central Europe for geodynamic investigations. The maintenance of the network includes coordinated programme of measurements, technical developments and international access to monitoring results for a long period of time. The Consortium fosters coordinated maintenance and upgrade of existing CEGRN sites, establishment of new ones, coordinated monitoring measurements, the operation and development of CEGRN Data Centre and Processing Centres.

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.

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.

Civil users of the NAVSTAR Global Positioning System (GPS) in Hungary are experiencing occasinal severe interference at the GPS signal frequency of 1575,42 MHz. As the application of the GPS technique spread rapidly in our country , radio frequency interference (RFI) should be considered a serious threat to widespread applications. The new geodetic control network (OGPSH) in Hungary is based on GPS measurements by which more than 1100 sites have been established. The paper reports the experiences gained during this work. Interference sources could be tracked to ground based telecom digital data transmissions which are operating mostly in Western part of Hungary. telecomminication regulations exceptionally allow such transmissions in specified countries. In order to warn potential GPS users mapping of the interference sources are being carried out.

The Central European Geodynamic Reference Network (CEGRN) based on GPS measurements has been established consisting of 31 sites in 11 Central European countries. Four epoch measurements were carried ouf spanning 3 years from 1994-97 . The results of the yearly epoch measurements on the CEGRN are the basis for a number of studies. There are 11 permanent GPS stations operating in the area. Nine multinational CERGOP Study Groups (CSG) are active and some of their resulfs are presented here. The CERGOP Data Centre is functioning efficiently andd smoothly in Graz, Austria. Processing of the observational data is carried out in the CERGOP Processing Centres (Bratislava, Frankfurt am Main, Graz, Matera, Pecny, Penc, Warsaw and Zagreb). The data analysis is done within CSG4. Imporant achievement is that the accuracy of the CEGRN epoch coordinates is on the sub-centimeter level. Based on CEGRN the Central European Terrestrial Reference Frame (CETRF) has been established as the result of activity of CSG3. Publication of the proceedings and results of the study groups is carried out by the Warsaw University of Technology, Poland, quickly and efficiently in the series Reports on Geodesy. We are aware of a number of local deformatio studies in the participating countries where CEGRN sites are used as reference. CERGOP has integrated a considerable part of geodynamic research in Central Europe, established a 1arge number of collaboration, exchange of information and perhaps most notably - multual trust and understanding among the participants.
