Introduction
The GNSS data from the EPN stations are freely available through the internet. Data are made available, depending on the station data policy :
The two Regional Data Centres (RDC), located at BKG (Federal Agency for Cartography and Geodesy, Germany) and at BEV (Bundesamt für Eich- und Vermessungswesen, Austria) provide access to the daily and hourly data from all the EPN stations.
In addition, ROB (Royal Observatory of Belgium), is maintaining the EPN historical data centre. This archive contains only daily RINEX data and the RINEX header has been changed to be in accordance with the site logs. The archive contains more historical data from the EPN stations (often for periods before the station was included in the EPN) than the Regional Data Centres, but it does not have the last 3-months of data available. Each month, ROB updates the archive with one additional month of recent EPN data.
The regional EUREF broadcasters (RB), located at BKG (Federal Agency for Cartography and Geodesy, Germany), ASI (Agenzia Spaziale Italiana) and ROB (Royal Observatory of Belgium) make available the EPN real-time data streams.
