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).

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

EUREF has classified MELI00ESP (Melilla, ESP) as a class A station which means that it can used as fiducial station for EUREF densifications.

The official ETRS89 coordinates used in ESP are maintained by CSG. This agency is fully responsible for the information kindly provided to the EPN:

 Valid (from - to) epoch t0 Position (m) Velocity (m/y) X Y Z VX VY VZ 074/2018- now 001/2017 5205628.368 -268411.259 3663428.135 NA NA NA

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].
