EGNOS improves GPS and makes air navigation safer Published on: 28/08/2013

News in RSS

Europe made its first venture into satellite navigation with EGNOS, a service which has significantly improved the accuracy of existing satellite positioning signals.

Now, huge advancements in aviation are also being made as EGNOS – already
available at more than 80 EU airports – enables more precise landings, fewer
delays and diversions and more efficient routes. The European Geostationary Navigation Overlay Service (EGNOS) increases the accuracy of the Global Positioning System (GPS) by providing positioning accuracy within three metres – GPS alone is only reliable to within 17 metres. Such precision has aided mapping, agriculture, location-based services and numerous other areas.
