Dear users,
The warnings starting from the 14th of February 2020 were not due to solar radio bursts.
Obviously because it occurs during the night time in Europe. The effect detected was due to a sudden change of the signal power of the GPS satellites of the block IIF and IIR-M. Description of the event here. This should not impact the GNSS applications. The change operated is still on and is now considered as the "nominal" mode, so that there is no longer 'abnormal' variation of the estimated index.

To detect Solar Radio Burst (SRB) affecting the GNSS signal reception in Europe, the carrier to noise density (C/N0) of the real-time EPN GPS network are monitored in near-real time (updated every 15 minutes). The intensity of the SRB impacts on GNSS applications are indexed at 4 levels:

  • quiet
  • moderate : SRB detected but should not impact GNSS applications,
  • strong : potential impact on GNSS applications,
  • severe : potential failure of the GNSS receivers.
