Description of the infrastructure

ROB hosts the Central Bureau of the EUREF Permanent GNSS Network (EPN, https://www.epncb.oma.be/) and performs the day-to-day management of the network (~360 stations).

The EUREF Permanent GNSS Network consists of a network of continuously operating GNSS (Global Navigation Satellite Systems, such as GPS, GLONASS, Galileo, Beidou, etc.) reference stations.

Data centres providing access to the station data.

Analysis centres that analyze the GNSS data.

Product centres or coordinators that generate the EPN products.

Central Bureau that is responsible for the daily monitoring and management of the EPN.

Use of this data base to retrieve ionospheric TEC using the ROB-IONO software.

Products

Since 2011, the ROB provides real-time ionospheric vTEC maps over Central Europe. Based on ~200 stations. The main products are 0.5°x0.5° grids of vTEC and vTEC variability available every 15 min with a latency of ~3 min. These maps can be consulted on a web interface (www.gnss.be) or downloaded in the IONEX format  (ftp://gnss.oma.be). Post processing available since 1998.

Well adapted for disturbed periods.

Also provided the Differential Code Biases of the GNSS stations.

Less than 10Mb/day

Since 2021, the ROB provide daily (less 1 day latency) vTEC estimation at Ionospheric Pierce Point from a selection of IGS stations (#220). The output consist in GNSS (GPS+GLONASS+GALILEO) sTEC and vTEC, as well as the DCBs for the different signal combinations every 30s.

More than 2Gb/day.
