18<strong>EGNOS</strong> – A boost to satellitenavigation in EuropeBy correcting errorssuch as those linked toionospheric disturbances, SBAS, likethe <strong>European</strong> Geostationary NavigationOverlay Service (<strong>EGNOS</strong>), make informationreceived from <strong>GNSS</strong> systems like <strong>Galileo</strong> <strong>and</strong>GPS even more accurate.<strong>GNSS</strong> systems alone do not meet the necessaryoperational requirements set by the civil aviationauthorities <strong>and</strong> the improved accuracy is alsobeneficial to all other uses of <strong>GNSS</strong> systems.As they are interoperable, SBAS systemshelp provide continuous coverageacross the globe.WAAS<strong>EGNOS</strong>SDCMGAGANThe <strong>European</strong> Geostationary NavigationOverlay Service (<strong>EGNOS</strong>) covers Europe <strong>and</strong> beyond.MSASThe USA uses the Wide Area Augmentation System (WAAS).Japan is covered by its Multi-functional SatelliteAugmentation System (MSAS).India also has its own SBAS, GAGAN, which coversthe Indian subcontinent.Also active in the field, covering the Russian Federation, is the RussianGLONASS System of Differential Correction & Monitoring – SDCM.All the SBAS are interoperable, so with the same receiver, users can benefitfrom augmentation of satellite navigation everywhere in the world.
