GNSS data repositories
EUREF data repository
In the frame of ROB’s services to the international EUREF Permanent GNSS Network and linked to the European Plate Observing System (EPOS) ESFRI, ROB operates the Historical EPN Data Center (EPN HDC) containing GNSS data of the EPN.
The data in this repository are collected by ROB from two international EUREF data centers, several regional data centers, or sent directly to ROB by data providers from all over Europe. The repository contains data from hundreds GNSS stations, coming from different agencies (from 37 countries mainly located in Europe). The EPN HDC repository contains data from 1996 until today (new data are added every day as part of ROB’s commitment to EUREF). All data in the repository have been available as open data, meaning that all data owners provided the data with the goal to make the data openly available for download (via https://www.epncb.eu/pub/obs/). Nowadays, at the end of the FAIR-GNSS project, EPN HDC data and metadata are available also through the Open data portal. ROB offers the data owners the possibility to provide information about data licenses, and a lot of effort has been devoted during throughout the FAIR-GNSS project to encourage data owners to attach a license to their data. Finally, the vast majority of the data has a license attached, whether CC0 or CC BY 4.0, which are licenses in agreement with the EUREF and EPOS data policy.
Belgian data repository
ROB also maintains a repository with the GNSS data from all Belgian ETRS89 GNSS reference stations contributing to EPOS and belonging to ROB itself and
- Digital Vlaanderen,
- Service Publique de Wallonie,
- Centre Spatial de Liège,
- Belgian National Geographic Institute .
ROB applied the EUREF standards to the Belgian data and, as one of the results of the FAIR-GNSS project, made it accessible to the public for the first time in 2023, via the Open data portal. The data in the Belgian repository, as is the case with EPN HDC data, consists of 1 or 2 daily data files for each GNSS station and containing observation data in the Hatanaka-compressed gzipped RINEX format (RINEX version 2 and/or version 3). RINEX is a community-agreed standard format for the exchange of GNSS data (used by all GNSS repositories all over the world).
