Global Navigation Satellite Systems Engineering, Policy, and Design
The European Geostationary Navigation Overlay Service (EGNOS) is Europe’s regional satellite-based augmentation system (SBAS). Used to improve the accuracy and reliability of GNSS positioning information, EGNOS is designed to provide safety of life navigation services to aviation, maritime and land-based users across the EU.

Europe has deployed two new Galileo satellites within its constellation, adding to the existing 26 operational satellites in orbit. The entry into service of satellites 27 and 28 follows an exhaustive 2022 testing campaign. In a recent communication, the European Space agency (ESA) said the new deployment will result in a measurable increase in positioning accuracy and improved overall performance of the Galileo system.
