Due to the occurance of coordinate jumps, the station coordinates given in the tables below are valid for a specific period in time (indicated in the first column). The coordinate jumps are caused by station-specific equipment changes (see station log and/or EPN_discontinuities.snx), but also by the switch from relative to absolute antenna models in the GNSS data processing (Nov. 2006). Consequently, station coordinates up to 315/2006 are compatible (and should be used) with relative antenna models while station coordinates after 316/2006 are compatible (and should be used) with absolute antenna models.

To obtain the station positions at an epoch t different from t0, apply the station velocities: X(t) = X(t0) + (t-t0)*VX; Y(t) = Y(t0) + (t-t0)*VY; Z(t) = Z(t0) + (t-t0)*VZ

The precisions indicated in the tables below are formal 1 sigma errors from the normal equation stacking. Due to the rounding, formal errors indicated by 0.000 m (0.0000 m/y) must be read as being smaller than 0.0005 m (0.00005 m/y) or 0.5 mm (0.05mm/y).

Following a recent initiative of the EUREF Technical Working Group (Monitoring of official national ETRF coordinates on EPN web), the differences between the national coordinates and the latest cumulative EPN solutions (section 1) are regularly monitored. They are given in two maps: [horizontal differences] and [vertical differences].
