The PECASUS consortium is one of the three global centers providing space weather advisories according to ICAO regulations. These advisories are sent to airliners using the existing aeronautical fixed network for international aviation.  For more information about that arrangement, see

Information about current space weather advisories are available from the Civil Aviation Weather Service by the Finnish Meteorological Institute.

According to ICAO regulations space weather advisories shall be issued only when very strong space weather events occur. As we are currently living the years of solar minimum, there has not yet been any need to send real advisories since Nov 7 2019, when the centers started their official operations. However, several test advisories have been sent during recent months in order to test the dissemination channels in the ICAO framework.

Besides PECASUS the two other services providing advisories are the Space Weather Prediction Center of NOAA ( and the ACFJ ( consortium formed by Australia, Canada, France and Japan.

The three centers are doing space weather monitoring in two week shifts with one of the centers serving as the On Duty Center (ODC) and the others as Primary and Secondary backup-centers.
