The European Terrestrial Reference System 1989 (ETRS89) is an
The development of ETRS89 is related to the global
The 89 in its name does not refer to the year of solution (realization), but rather the year of initial definition, when ETRS89 was fully equivalent to ITRS. The solutions of ETRS89 correspond to the ITRS solutions. For each ITRS solution, a matching ETRS89 solution is being made. ETRF2000, for example, is an ETRS89 solution, which corresponds to ITRF2000. ETRS89 is realized by EUREF through the maintenance of the EUREF Permanent Network (EPN) and continuous processing of the EPN data in a few processing centres. Users have access to ETRS89 via EPN data products and real-time streams of differential corrections from a set of public providers based on the EPN stations. The transformation from ETRS89 to ITRS is time-dependent and was formulated by C. Boucher and Z. Altamimi [2][3]
