Space weather and GNSS monitoring services for air navigation

The SWAIR service aims at providing early warning, forecast and performance assessment of GNSS signal, at a local level, for the Air Navigation sector. The service's objective is to increase confidence of air operators in using EGNOS and GNSS signals. It addresses the problem of intentional and unintentional interferences and Space Weather events which can influence the performance and reliability of a variety of positioning systems. SWAIR also assesses the sources of GNSS signal vulnerability in order to develop mitigation activities. The product furthermore addresses the problem of the peripheral boundary of EGNOS and GNSS landing without SBAS coverage. The service mainly targets aviation entities such as air navigation service providers (ANSP), airports, civil aviation authorities (CAA), and airlines.
