EUREF Permanent Network
The EUREF Permanent Network (EPN) is a
science-driven network of continuously operating GNSS reference
stations, covering the European continent,and with precisely known
coordinates in the ETRS89.
All contributions to the EPN are voluntary, with more than 100
European agencies/universities involved, and the reliability of the
network is based on redundancy and extensive guidelines guaranteeing
the quality of the raw GNSS data to the resulting station positions.
EPN products are station positions and velocities in the ITRS and
ETRS89, the analysis of the station position time series and
tropospheric zenith path delays.
