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).

1. POSITIONS/VELOCITIES PUBLISHED BY EUREF

EUREF has classified BELF00GBR (Belfast, United Kingdom) as a class B station and consequently it should NOT be used as fiducial station for EUREF densifications.

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].
