Aeronautical Meteorology Programme - Legacy Site

Earlier today a space weather information service for international civil aviation became operational. The launch of the operational service is the culmination of many years of work by the International Civil Aviation Organization (ICAO), World Meteorological Organization (WMO), their Members, service providers, partner international organisations and other agencies. 

The service is provided in accordance with the requirements of ICAO Annex 3/WMO-No. 49, Technical Regulations, Volume II - Meteorological Service for International Air Navigation. The service is delivered on a worldwide basis by three designated global providers - namely, a pan-European consortium known as PECASUS (comprising Austria, Belgium, Cyprus, Finland, Germany, Italy, Netherlands, Poland and the United Kingdom), a ACFJ consortium (comprising Australia, Canada, France and Japan), and the United States. The global service will be augmented by regional capabilities offered by China, the Russian Federation and South Africa at a later stage.

The service ensures space weather advisory information is disseminated to aviation user worldwide, on a 24/7 basis, through the aeronautical fixed network in instances of moderate or severe impacts of space weather phenomena of solar origin, in particular with respect to high-frequency (HF) communications, global navigation satellite system-based (GNSS) navigation and surveillance, satellite communications and augmented radiation aboard aircraft.
