The EUREF Permanent Network (EPN) is a network of more than 350 continuously operating GNSS stations installed throughout the European continent and offshore, managed by EUREF. The EUREF is a sub-commission of the International Association of Geodesy (Sub-commission for Europe, sub-commission 1.3a of Commission 1 of the IAG). The major goal of the EPN together with its densifications, is to realize and ease the access to the ITRF/ETRS89 frames (following the INSPIRE Directive) in Europe. To properly deal with this and the involved tasks in general GNSS processing, several components and Working Groups are involved under the umbrella of the EUREF GB. Currently the following WGs are active:
European Dense Velocities Working Group (2017-now): Chaired by E.
Brockmann EPN Densification Working Group (2015 - now): Chaired by A. Kenyeres Deformation Models Working Group (2012-now): Chaired by M. Lidberg Multi-GNSS Working Group (2012-now): Chaired by E. Brockmann EPN Reprocessing Working Group (2009 - now): Chaired by C. Völksen EPN Real-Time Analysis Project (2008 - now): Chaired by W. Söhne One of the most demanded products by a variety of communities, such as geomatics, surveyors, space geodesy,… are the GNSS dense networks, in this case, the EPND. The EPND consists of +2500 high-quality permanent sites over different countries that are operationally computed and provide results on a daily/weekly basis. In this paper, we briefly introduce the EUREF GB and focus on the activities carried out by the EPN Densification WG. Preliminary results of the EPND 2200, the latest release of the strongly established Densification solution, based on stacking weekly solutions, and a complementary solution, currently under development, based on considering individually the solutions provided by different partners are shown.
