Guidelines for EUREF Densifications
2021This document outlines the procedure for computing station coordinates (and velocities) in the ETRS89 (European Terrestrial Reference System), in particular in the framework of national densifications of the ETRS89. The document also describes how to proceed to request a EUREF validation of the densification.

Recomputation of EUREF GPS Campaigns in Slovenia
2004A new recomputation of the three EUREF GPS campaigns, carried out on the territory of Slovenia, was performed. All the three campaigns were processed in the ITRF 96 at the mean epoch of each individual campaign, starting from raw data. Final IGS orbits and Earth rotation parameters were transformed from their original reference frames to ITRF 96 ...

Results of the EUREF 1994 Croatia and Slovenia GPS Campaign
1996The EUREF 1994 CROATIA and SLOVENIA GPS campaign was carried out in May-June 1994, including fifteen new sites. The coordinates of the new sites are given in TRF92 (epoch 1994.4) and the EUREF’89 reference frame. The computation were performed in Frankfurt with the Bernese GPS Software version 3.4 by assistance of two colleauges from Zagreb.
