European Global Navigation Satellite System (EU GNSS)


European Global Navigation Satellite System (EU GNSS) Europe is building its very own state-of-the-art Global Navigation Satellite System (GNSS) to provide accurate and guaranteed positioning for all types of civilian applications: including car navigators, mobile phones, maritime, road, rail and air transport. Galileo is a global navigation satellite system (GNSS) currently being built by the European Union (EU) and European Space Agency (ESA).


Galileo is the EU’s state-of-theart global navigation satellite system under civilian control, providing accurate navigation signals everywhere in the world. Thirty satellites, including spares, and the necessary infrastructure on the ground will make up the system when it is fully up and running in 2018. Initial services will be provided based on the first constellation of 18 satellites as of 2014. Galileo will ensure Europe's independence in a sector that has become critical for its economy and the well-being of its citizens.


European Geostationary Navigation Overlay Service (EGNOS), Europe's first venture into satellite navigation, improves the open public service offered by the USA's Global Positioning System (GPS) and Galileo by increasing accuracy. GNSS systems alone do not meet the necessary operational requirements set by the civil aviation authorities and the improved accuracy is also beneficial to all other uses of GNSS systems. As they are interoperable, satellite-based augmentation system (SBAS) help provide continuous coverage across the globe.
