The EUREF-FIN reference frame is based on the Finnish Permanent GPS Network FinnRef®. Four FinnRef® stations belong to the European-wide GPS network (EPN, European Permanent GPS Network). In 1996-1997 FGI measured a GPS network of 100 points. This network was connected to the EUREF reference frame via FinnRef®. Most of the measured points were old 1st order triangulation points and the measuring sessions were at least 48 hours. The results were presented in the EUREF meetings in 1998 (Bad-Neuenahr, Germany) and in 1999 (Prague, Czech). In the latter meeting 19 points were accepted as a part of the European wide EUREF network. Definition of the EUREF-FIN reference frame is done with the permanent GPS network FinnRef® and the network of the 100 points. In 1998-1999 FGI densified this network by measuring 350 points in order to offer an easier accessible points for practical use. Points were selected mainly from lower order points of the National Land Survey. The selection criteria were accessibility and good GPS visibility. The session lengths were six hours. In this publication we present the coordinates of the 100 points defining the EUREF-FIN reference frame in Finland as well as the coordinates of the 350 densification points.
