GNSS-based Space Weather

Ionospheric Products

• Statistical Maps and Plots: statistics to compare the ionosphere for a requested time with respect to the 15 previous days.
  
• VTEC Time Series: the VTEC evolution over time and its median of the 15 previous days (24h prediction), extracted from the VTEC maps at 3 different locations (North of Europe, Brussels and South of Europe).
  
• ROB Products are publicly available in IONEX format at https://gnss.be/SpaceWeather/Products/IONEX. We request that users include a citation or an acknowledgment when using ROB products. See disclaimer and copyright for more information.

Solar Radio Burst Warnings for GNSS Applications in Europe

Solar Radio Bursts (SRB) emitted at the GNSS frequencies can affect the GNSS signal reception. To detect such event, a SRB warning system (currently under maintenance) with a 4-level index is set in Europe using the EUREF Permanent Network.

Projects and Collaborations

We participate to the PITHIA-NRF project (Plasmasphere Ionosphere Thermosphere Integrated Research Environment and Access services: a Network of Research Facilities), providing expertise with GNSS data analysis in real time, information on the state of ionosphere above Europe and alert concerning the fade out of C/N0 parameters due to Solar Radio Bursts.
