EGNOS (European Geostationary Navigation Overlay Service)

EGNOS, or the European Geostationary Navigation Overlay Service, is a satellite-based system that enhances the accuracy and reliability of GPS signals across Europe. It uses geostationary satellites to provide corrections to GPS data, improving positional accuracy to within a few meters. EGNOS helps in various applications such as aviation, maritime navigation, and land transportation, making these services safer and more efficient. It is essential for precise navigation and is part of Europe’s efforts to ensure reliable satellite navigation technology.
