☀️ Space weather 🛰️ GNSS signals 📊 ROB monitoring
The Royal Observatory of Belgium uses GNSS observations to monitor
- the influence of the Sun on the ionosphere over Europe in terms of Total Electron Content (TEC)
- the influence of solar radio bursts on GNSS observations
To do this, multi-GNSS observations from the EUREF Permanent Network are used.
The products below provide near-real-time information on ionospheric conditions and intense solar radio emissions affecting GNSS.

☀️ Solar Radio Bursts
Monitor solar radio bursts that can affect GNSS signal reception
Strong radio emissions from the Sun can interfere with GNSS signals and, in severe cases, affect receiver tracking.
