EUREF Permanent GNSS Network

EPN station positions and velocities:

The most recent reference frame product published is the multi-year position and velocity solution C2385. The C2385 solution is covering a time span from 1996-01-01 (GPS Week 0834) to 2025-09-27 (GPS Week 2385). It provides the most accurate positions and velocities for the EPN GNSS stations.

The station positions and velocities given in the tables below are valid for a specific period in time (indicated in the first column). Indeed, station positions can be affected by sudden position changes also call discontinuities mainly caused by station-specific equipment changes. In addition, it is possible that the velocity of the station change in time. To obtain the station positions at an epoch t different from t₀, apply the station velocities:

X(t) = X(t₀) + (t-t₀)*V_X

Y(t) = Y(t₀) + (t-t₀)*V_Y

Z(t) = Z(t₀) + (t-t₀)*V_Z
