Augmentation
Any technique of providing enhancement to GNSS in order to provide improved navigation performance to the user.
– Satellite-based augmentation system (SBAS). A system providing additional satellite signals in order to enhance the performance of the GNSS service. (e.g. Wide Area Augmentation System (WAAS, US); European Geostationary Navigation Overlay Service (EGNOS); Multi-transport Satellite Augmentation System (Japan); GPS Aided Geo Augmented Navigation system (GAGAN, India)
– Ground-based augmentation system (GBAS). A system providing additional signals from a ground-based station in order to enhance the performance of the GNSS service. (e.g. IALA DGNSS beacon system)
