EUREF – Reference Frame Sub Commission for Europe

EUREF (Reference Frame Sub-Commission for Europe) develops and maintains the European Terrestrial Reference System (ETRS89) as the regional densification of the ITRF in Europe. It provides high-precision coordinates and time series for GNSS stations across Europe. EUREF ensures compatibility with the ITRF while supporting European geodetic, mapping, and positioning needs.
