Abstract: The Metadata Management and Distribution System for Multiple GNSS Networks (M3G, https://gnss-metadata.eu), hosted by the Royal Observatory of Belgium, is one of the services of the European Plate Observing System (EPOS, https://www.epos-eu.org) and EUREF (http://euref.eu). M3G provides the scientific as well as the non-scientific community with a state-of-the-art archive of information on permanently tracking GNSS stations in Europe, including the station description, and the GNSS networks the stations contribute to. Since its first public release (2018), M3G has been under continuous development, to respond to the evolving needs of the GNSS community. M3G offers APIs and an interactive user interface where any GNSS station manager, after registration, can insert all information relative to its GNSS stations and make this information publicly available. Consequently, the commitment of station managers to insert GNSS station metadata in M3G and their willingness to keep the information up to date is crucial for the success of M3G. At the moment, M3G is used by 131 GNSS agencies and includes data from more than 2600 GNSS stations all over Europe, and more are still in the process of being collected. We will illustrate the rationale underlying M3G, the data that it provides and how these data can be accessed.
