Agencies wishing to contribute to the EPN Densification are invited to contact Ambrus Kenyeres, FOMI Satellite Geodetic Observatory, kenyeres@sgo.fomi.hu.

Analysis Centres interested in joining the EPN Densification are expected to submit at regular intervals daily or weekly SINEX position solutions to A. Kenyeres (EUREF will not distribute these SINEX files). In addition, the Densification Analysis Centres maintain a densifcation form (for example SGO.OC) which contains at least the list of stations (EPN and non-EPN) that are included in their solutions.

Operational Centres interested in joining the EPN Densification are expected to provide the RINEX data of national or regional network of GNSS stations to one of the EPN Densification Analysis Centres (these RINEX data are not distributed by EUREF) and in addition submit and maintain the station site logs to the EPN CB using the on-line station log submission tool. Contributing Operational Centres maintain a form (for example SGO.OC) with the list of stations for which they take the responsibility to provide meta-data to EUREF. This list can contain EPN stations as well as EPN Densification Stations.

In many cases, the Densification Analysis Centre is also acting as an Operational Centre.
