the European Geostationary Navigation Overlay Service (EGNOS) uses additional ground stations being used to enhance the accuracy and reliability of existing satnav services across a given geographic regions. Signal error measurements or integrity warnings highlighting reliability problems are then relayed to geostationary satellites for rebroadcast to users – available to any suitably equipped receiver. The resulting performance enhancements allow satnav to be employed for ‘safety of life’ services, especially aviation, but also any application requiring high precision.
