Space weather (SWX) can affect a number of things, such as Global Navigation Satellite System (GNSS) and high frequency (HF) and satellite communications, and can increase exposure to harmful radiation for flight crew and passengers.
ICAO acknowledged this impact to operations in 2011 when the development of concept of operations (CONOPS) for space weather was started. This process resulted in the audit and selection of three global space weather centers by the ICAO council in November 2018 and the start of operations planned for November 7, 2019.
PECASUS, a consortium of European providers led by FMI, is one of the three Global Space Weather Centers (SWXC).
PECASUS will provide civil aviation with data on space weather that could affect communications, navigation and the health of passengers and flight crew.
More information about space weather can be found in ICAO Manual on Space Weather Information in Support of International Air Navigation (Doc 10100) and on the web pages http://pecasus.eu/, https://spaceweather.com, https://www.spaceweatheralerts.com
