AB This article contains an analysis of GNSS (Global Navigation Satellite System) integrity from a viewpoint of railway transportation. The integrity concept of functional EGNOS (European Geostationary Navigation Overlay Service) system is explained in detail and also the integrity mechanism of the future Galileo system is briefly outlined. In order to verify the theoretical conclusions, static measurements by means of EGNOS receiver in a safety mode have been performed. Selected experimental results are discussed.
