Ten years of safer skies with Europe’s other satnav system

With 26 satellites in orbit and more than two billion receivers in use, Europe’s Galileo satellite navigation system has made a massive impact. But our continent has another satnav system that has been providing safety-of-life services for ten years now – chances are that you’ve benefited from it without noticing.

EGNOS

EGNOS

Its name is EGNOS, the European Geostationary Navigation Overlay Service. Transmitting signals from a duo of satellite transponders in geostationary orbit, EGNOS gives additional precision to US GPS signals – delivering an average precision of 1.5 metres over European territory, a tenfold improvement over un-augmented signals in the worst-case – and also confirmation of their ‘integrity’ – or reliability – through additional messaging identifying any residual errors.

GPS III introduced on EGNOS services

Introduction of the first GPS III satellites into EGNOS services was successfully achieved on 27 July 2020, following the initiation by GPS of a transition from its “GPS Block II” satellites to its new generation “GPS Block III” satellites.

The EGNOS SoL service has improved following the successful GPS III introduction

The GPS operational constellation started in 2020 to migrate from GPS II satellites to the new generation GPS III satellites. Through cooperation exchanges with the US, the European Commission and the European GNSS Agency (GSA) obtained assurance on the “backward compatibility” of the GPS III satellites with regard to GPS II, and in particular concerning their failure characteristics.

Webinar: EGNOS – free accuracy for mapping and GIS applications

The webinar, June 20 @ 10:30 am – 11:30 am CEST, is organised by EuroGeographics and European Global Navigation Satellite Systems Agency (GSA). The goal of the webinar is to brief users from mapping and GIS communities about EGNOS, the European free augmentation service that improves GPS accuracy up to sub-meter range for mapping and GIS applications.

New technology version of EGNOS will harness Galileo for aviation

EGNOS V3 Contract signing

EGNOS V3 Contract signing

The next generation of Europe’s satellite navigation overlay service, EGNOS, will combine use of GPS and Galileo signals to improve accuracy and robustness of navigation for air traffic and other uses where lives are at stake.

A contract was signed on 26th January at ESA’s technical centre in the Netherlands for the second  generation  of the European Geostationary Navigation Overlay Service, EGNOS V3, planned to enter service in 2025. Read more…

EGNOS protects GNSS timing

The European GNSS Agency (GSA) announces that the EGNOS time service remained stable and properly synchronised to UTC time during a recent GPS timing anomaly on January 26th.

On the 26th of January, users of United States GPS system experienced timing issues after a number of GPS satellites broadcast incorrect UTC correction parameters. According to the US Air Force, the coordinated universal time message that was transmitted was off by 13 microseconds. During this anomaly EGNOS, which serves as an augmentation to the GPS, remained stable and properly synchronised to UTC. Read more…
