EGNOS

Making satellite navigation sufficiently accurate by improving its integrity for aircraft to rely on, the European Geostationary Navigation Overlay System, EGNOS, is today employed by hundreds of airports across our continent, guiding airliners down through all weathers to the point where pilots gain sight of runways to initiate landing. Now an upgraded version of the system, EGNOS v3, has passed its Critical Design Review – putting it on track to enter service by the second part of the decade.

“The successful review confirms that the multi-constellation, multi-frequency EGNOS v3 will be a significant push forward in satellite augmentation,” commented Javier Benedicto, ESA's Director of Navigation. “Directing aircraft from the sky instead of the ground, our continent’s own satellite navigation augmentation system has been serving airports, pilots and passengers for more than 11 years now. The coming EGNOS v3 will mark a significant step forward enlarging EGNOS accuracy, robustness and overall coverage, thanks to its use of multiple frequencies from both GPS and Galileo.”
