The European Geostationary Navigation Overlay Service (EGNOS) recently passed an important milestone where the initial performance of the service was successfully reviewed.
Used to improve the performance of satellite navigation systems for the most safety-critical applications such as navigation and aircraft landing, EGNOS is Europe’s regional satellite-based augmentation system (SBAS).
This new V3 generation of EGNOS, currently under development by Airbus, will introduce new services based on multiple frequencies from multiple constellations (GPS, Galileo), and will embed sophisticated security protection against cyberattacks.
EGNOS V3 will improve navigation and safety for more destinations in Europe.
System performance evaluation for initial services highlighted the high level of maturity of the design and its suitability to seamlessly continue the provision of critical navigation services, such as precision approach and landing everywhere in Europe, whether or not airports are equipped with expensive instrument landing systems (which is often not the case for smaller ones).
The review confirmed that EGNOS V3 will provide the accuracy, continuity, integrity and availability required for life safety operations up to Cat.I – with margins.
“At this stage of development, this performance evaluation has demonstrated the increased benefits that EGNOS V3 should bring to Europe,” said Didier Flament, Head of EGNOS & SBAS Division at ESA. “As the full power of this new generation EGNOS remains to be qualified in the next phase of the project, this first important step in the Detailed Design phase has met our expectations on all the heritage aspects assessed. We look forward to the next steps, as we are convinced that EGNOS V3 will meet expectations.
Additionally, the use of Galileo and GPS signals to monitor ionosphere-induced position errors increases service availability in the western and southwestern periphery of Europe. This expands the area in which satellite navigation landing becomes possible without the need for dedicated ground systems.
“The consolidation of EGNOS’ service area will benefit our customers as it will support their satellite navigation guided operations to even more destinations,” said Hugues de Beco, ATM Programs Manager at EGNOS. Airbus Commercial Aircraft. “Airbus is very pleased to support the growth of EGNOS users in commercial aviation in Europe with the recent certification of SBAS landing systems on the Airbus A320 and A330 families. We continue to support the development of any system that will contribute to safer and more sustainable air traffic.
