Partner UNIPD is responsible for WP6 Time series analysis and provides support to a number of other related WP's. The output of WP6 is foreseen every third month, beginning month 6. At this stage (month 18) we report on the successful generation of time series for all the permanent stations for which we have the data available, that is the EPN stations plus a number of Austrian and Italian permanent stations which are not part of the EPN. Our analysis includes the statistical and spectral analyses of the time series, whenever it is meaningful, i.e. for time series longer than 3 years. The analysis is based on the processing of normal equation files. Each one of them is obtained from the combination of two normal equations for each week, and the multi year solution embodies constraints on the position and velocity datum which are considered as state of the art. According to this combination scheme, more normal equations can be combined, yielding a unified network. We have also developed the presentation and communication framework for our results, in the form of a web page. As soon as time series for other permanent stations in the study area are available, they can be processed accordingly. A number of activities have been done in the support to other WP's. More precisely we have supported WP1 as follows: o Raw data (RINEX) from the newly established stations ASIA and ROVI are sent regularly to the Project's Data Center in Graz; o Processed (NEQ/SNX) files from a network including permanent stations relevant to the Project have been sent to the Project's Data Center and to the responsible of WP5, to prepare the basis for the time series which will be the input to WP6.

Within CERGOP-2/ENVIRONMENT project, a special attention is given to geodynamics models development for specific regions from countries that participate to the present project. For this goal, study groups were created (WPs-l0.x) which has the main objectives to monitor recent crust movements, to detect the borders of the tectonic plates and to quantify their three dimensional movement rates. These studies require a close cooperation between geodesists, geologists and geophysicists. In 1996 the Collaborative Research Center (CRC) 461 "Strong Earthquakes: A Challenge for Geosciences and Civil Engineering" was founded by the Deutsche Forschungsgemeinschaft (German Research Foundation) as a German contribution to the UN initiative "International Decade of Disaster Reduction" (IDNDR). A central project, of this CRC, is the subproject BI "Three Dimensional Plate Kinematics in Romania", which studies the deformation determination ofgeotectonic units in the Vrancea Region (epicenter zone of earthquakes from Romania). In this purpose, there were accomplished by repeated GPS-measurements within a network which has been installed in 1997 - Fig. 4 (Ghitau, 1997, Dinter & Schmitt, 1999, et al.) and measured in 1997, 1998, 2000, 2002 and 2003. This network was formed, at the beginning, by 26 stations, covering an area of 250 km x 380 km having the Vrancea area as the centre. At present, the studied region is enlarged to southern part of Romania and contains much more points. The geodetic DATUM is given by stations of the CEGRN the CEI-initiative CERGOP.

Activities on this work-package subgroup include preparation activities at the University of Zagreb, Faculty of Geodesy and field reconnaissance in the area of the Plitvice Lakes National Park. The combination of equipment has been tested in the field and it is now ready to be deployed in the Plitvice Lakes test area. The goal is to measure the Lake Kozjak with the combination of precise bathymetry and RTK GPS (Real Time Kinematics). In the area of Plitvice Lakes, we were looking for the best positions (sky clearance, obstacles, satellite visibility, ground stabilization) for future geodynamic GPS-measurements. At the same time, we have chosen the points which will be used as base points for hydrographic measurements using the RTK-method. The cooperation with the Croatian Hydrometeorological Institute was established in order to compare the datasets of previous hydrological measurements with current situation in the Lakes. In cooperation with the tectonic experts we prepare the structural map of the area of the Plitvice Lakes in order to find better explanation for possible movements of tectonic units in the area. The geological situation is particularly important for hydrologic assessment since the loss of water (lowering of water level) in the lakes is caused by faults.

The geodynamic investigation of the Tatra Mountains crust movements is a local subproject of the CERGOP-2/Environment supported by the European Union. This contribution analyzes repeated epoch measurements performed in a special GPS network in order to investigate tectonic motions within the Tatra Mountains region. This GPS network was established in 1998 and consists of 11 sites, 7 in Slovak Republic and 4 in Poland. The size of the investigated area is approximately 40 km by 60 km with maximum relative height difference 1800 m between sites. Epoch measurements were performed annually from 1998 to 2003. Processing of all GPS campaigns was done using the Bernese software 4.2 with the standard procedure. All GPS campaigns were connecting to the nearest five IGS GPS permanent stations. For determination of the velocity vectors two models were used.

Looking at the geologic map (Fig.l) and the geotectonic division (inside scheme of Fig.l) of Europe we can see, that the area investigated by the 7 groups for regional investigation (WP 10.1 to WP 10.7) of the CERGOP - 2 work package WP 10 "Geodynamics of Central Europe" (see tab. 1 for subjects and chairs) belong almost exclusively to the Alpine Europe, called also Neo-Europe. More exactly it belong: to the Eastern Alps-Carpathian-Balkan of the northern and the Dinaric Alps of the southern branches, of the European sector of the Alpine-Himalayan erogenic belt, with the Pannonian Basin in between. The forefield of the Eastern Alps-Carpathian-Balkan Alpine fold-and-thrust belt is very heterogenous and comprise tectonic units of Hercynian (e.g. Bohemian Massif of Czech Republic including the marginal Sudetic structures of Poland), Caledonian (e.g. within the Transeuropean Suture Zone - TESZ - of Poland), and Precambrian (Podole-Moldavian sectors of the East-European Platform of the Ukraine and Romania). These were described in great details in a series of monographs published in Reports on Geodesy by the Chief Editor J. Sledzinski as results of the CERGOP-1 Study Group CSG 8 "Geotectonic analysis of the region of Central Europe".

This paper summarizes some effects that influence the estimation of station coordinates in case of no physical movement of the station itself. The examples of receiver tracking performance, antenna phase center variation and reliability of tropospheric estimation are assessed in detail. For the first effect the results of performance tests of the newly introduced GPS receiver Leica GRX1200 and the antenna Leica AX1202 are presented. The second effect is summarized in a section about the different types of antenna phase center corrections and respective calibration techniques. Within field tests the sensitivity and repeatability of antenna phase center variation were assessed. Thirdly, the results of a field experiment including GPS and microwave radiometry are presented to evaluate the reliability of tropospheric estimations and GPS derived station heights.
