Abstract: The International Association of Geodesy (IAG) Reference Frame Sub-Commission for Europe, EUREF, merges efforts of National Mapping and Cadastral Agencies (NMCA), Universities and research institute to define, realize and maintain the European Terrestrial Reference System 1989 (ETRS89) and the European Vertical Reference System (EVRS) for scientific and practical purposes in Europe. These systems are the basis for geo-referencing in Europe and have been endorsed by the European Union INSPIRE directive (Infrastructure for Spatial Information in the European Community), Eurocontrol and EuroGeographics. The realization, maintenance and development of the ETRS89 is primarily done through the EUREF Permanent GNSS Network (EPN). EPN consists of continuously operating GNSS stations (~340 stations), supported by Data and Analysis Centres and a Central Bureau that is responsible for the monitoring and management of the EPN. All contributions to the EPN are provided on a voluntary “best effort” basis, with more than 100 European agencies/universities involved. The EPN operates under well-defined standards and guidelines which guarantee the long-term quality of the EPN products. In response to an increasing demand both from the National Mapping Agencies and research groups, the backbone EPN has been complemented with additional national CORS networks with rigorously computed station coordinates and velocities. At present, the dense European network incorporates ten times more stations as the core EPN sites and benefits from the contribution of 26 different Institutions. The physical height system EVRS is realized through common adjustment of the Unified European Levelling Network (UELN) where the vast majority of the European countries.
