Within the Central Europe Regional Geodynamics Project (CERGOP) for the establishment of a high precision reference frame CEGRN (Central European GPS Geodynamic Reference Network) eight GPS campaign solutions since 1994 are available for velocity estimation. They were used to compute preliminary station velocities in the ITRF2000. This paper reports not only on the results and some comparisons with former solutions published by the CERGOP group but also on the improved options available for velocity estimation with version 5.0 of Bernese GPS Software.

Central Europe Regional Geodynamic Project (CERGOP) in Slovenia includes GPS measurements on 5 sites. Within the first part of the project during years 1994-1997, measurements were performed on one site (Ljubljana), and during the CERGOP-2 extension in years 1999-2005 additional 4 sites were added (Božica, Malija, Snežnik and Mrzlica). However, till now measurements on the three sites only (Ljubljana, Božica and Malija) have been completed. Obtained data show similar sense and amount of horizontal displacements. They exhibit general northward movement of sites at the average velocity of 3 mm/yr. This is in accordance with results obtained from other sites of cirkum-Adriatic region, and it confirms the northward movement of the Adriatic microplate towards the “stable” Eurasian plate. In Slovenia, a northward oriented δ1 tensor have been also obtained from several tens of earthquake fault plane solution. Slight defferences in sense and velocity of displacements among particular sites could be explained by the influence of local structures. In Slovenia, they belong to the Periadriatic dextral shear zone, to the Dinaric dextral shear zone, and to the Transdanubian sinistral shear zone. However, the real dynamics of particular structures, among which some also express co-seismic creep, will be possible to determine only by GPS measurements over a denser network of sites.

Researchers from the Faculty of Geodesy, University of Zagreb, organized and performed various research activities within the project CERGOP2/Environment. The participation in both CEGRN campaigns was ensured with two epoch stations: Brusnik and Hvar. Activities related to the working package 10.4: International geodynamic test area Plitvice Lakes included several hydrographic measurements with the combination of GPS positioning and echosounder bathymetry. Repeated measurements with two frequencies yielded new insight about the sediments on the lake bottom. A structural map of the Lakes has been prepared, too. Geodynamic measurements has been performed on several special points. The foundation for future permanent station in the area of the Plitvice Lakes has been prepared.

Determination of deformations parameters from CERGOP GPS observations campaigns are presented at the poster. The velocity vectors are determined for CERGOP stations participated in GPS observations campaigns in the period 1994-2005. In the period of 11 years, 7 GPS observation campaigns were executed. Good quality of observations and data processing create chance to determined precise value of velocity and deformations like main directions of deformations and elongation (distortion). Method used for computation of deformation was proposed by Altiner. Comparison of deformation parameter with a European stress model made by Jarosiński is also presented in the paper.

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.

This paper summarizes the recent works with respect to the CERGOP-2 project tasks. The main activity was the implementation of the Working Package "Geodynamics of Balkan Peninsula". Major efforts were taken to the maintenance of the operation of two permanent GPS stations in Bulgaria and to arrange for the data transmission to the CERGOP Data Centre in Graz. The CEGRN GPS campaigns of 2003 and 2005 were analyzed together with additional Balkan Peninsula stations. New results on coordinates and velocities for this Balkan Peninsula subnet of CEGRN are computed and will be presented and discussed. The accomplished works on the monograph "Geodynamics of Balkan Peninsula" with the preparation of the manuscripts and the main content of the findings will be outlined.

ASI/CGS contribution to CERGOP II project covered the following topics: landslide monitoring, production and quality check of zenith total delays estimated for a global as well as regional GPS networks devoted to meteorology applications, RTK and navigation tests, critical analysis of GPS long time series helpful for geodynamic as well atmospheric investigations. For what concern the landslides monitoring the two sites under investigation: Aliano and Avigliano are located in Basilicata region, (South of Italy). These sites are affected by a dramatic creep of the ground which in the past was the cause of severe damages to the buildings and roads in the areas. We will show the state of art of the activities comparing GPS with Perrnanent Scatter IN-SAR technique For what concern the routine production of ZTD we will show a critical comparisons of our solutions with radio balloon observations and a discussion about the assessment of their reliability. Finally the results of a navigation experiment by using differential correction provided by EUREF-NTRIP service will be shown.

GPS observations are still intluenced by a whole amount of effects, as for example multiple reflections, ionosphere etc. which have an impact on the accuracy of the observables even on carefully selected sites. Up to now these effects can not be mitigated or modelled satisfactorily. Hence the monitoring of these station specific effects is mandatory in order to judge about data quality and derive weighting or deletion schemes for optimal parameter estimation. Within the tasks of the work package 4 of the Central Europe Geodynamics Project (CERGOP), a software tool was developed to monitor the continuously operating reference stations of the network. The development was carried out using C++ libraries available for the most common operating systems. Here we describe the basic features of this package and give an overview of its present status.

The region of sub project Crustal Movements in the Eastern Alps and Northern Mediterranean is one of the most interesting geodynamic areas. There were a lot of very strong earthquakes in Europe. Therefore was already some local network stabilised and observed. In frame of CERGOP 2 is established WP 10.1. Presented is in tectonics of central region; Slovenia and Istria. on base of uphill now measurements was selected some point covering all region.
