Royal Observatory of Belgium

The Royal Observatory of Belgium (ROB) is a Belgian federal scientific institute with major activities in geodesy and geophysics, particularly in GNSS, terrestrial reference systems, Earth rotation, crustal deformation, and gravimetry. ROB operates permanent GNSS stations, contributes to international reference frames, and plays a key role in European geodetic infrastructure, notably through the EUREF Permanent Network (EPN) and EPOS-GNSS, including GNSS data, metadata, quality monitoring, and analysis.
