The EPN station coordinates and velocities result from the regular time series analysis and are the most accurate and up-to-date solutions for the EPN sites. They are used for the maintenance of the regional densification of the ITRFyy between successive ITRFyy release and for the maintenance of the ETRS89:

  • EPN station coordinates and velocities in the ETRF2014 (class A and class B)
  • EPN station coordinates and velocities in the latest realization of the ITRS: IGS14 (class A and class B)

Horizontal Velocities
ETRF2014 horizontal velocity field derived from the latest EPN cumulative solution. In the ETRF2014, the horizontal velocities are expressed with respect to the Eurasian plate. The Eurasian plate rotation model from ITRF2014 (Altamimi et al., 2017) has been used. The green dots on the map indicate the youngest sites (less than 3 years of observations), which have unrealistic velocities.
Vertical Velocities
The ETRF2014 vertical velocity solution derived from the latest EPN cumulative solution. The uplift is indicated red, subsidence with blue arrows. The green dots on the map indicate the youngest sites (less than 3 years of observations), which have unrealistic velocities.
