EGNOS - Europe’s first venture into satellite navigation

The European Geostationary Navigation Overlay Service (EGNOS), improves the accuracy of GPS over Europe making it suitable for safety Citizens can profit from better personal GPS navigation provided that they use an EGNOS-enabled receiver (as most of the recent models do).

The EGNOS system works using 34 ranging and integrity monitoring stations (RIMS) that receive signals from the US GPS satellites. Four mission control centres handle data processing and differential corrections counting and six navigation land earth stations manage accuracy and reliability data for sending to the three geostationary satellite transponders for relay to end-user devices. EGNOS offers 3 services:

1. Open Service: free and open for anyone with an ‘EGNOS-enabled’ GPS device.

2. Safety-of-life Service: provides an ‘integrity’ message warning the user of any malfunction of the GPS signal in 6 seconds. This is essential when satellite

navigation is used for applications where lives are at stake. EGNOS was certified for civil aviation in 2011.

3. The EGNOS Data Access Service (EDAS): provides EGNOS information in real time over the internet.


EGNOS is the first pan-European satellite navigation system. Similar services are provided in North America by the Wide Area Augmentation System (WAAS) and in Japan by the Multifunctional Satellite Augmentation System (MSAS).
