Launched onboard EUTELSAT’s Hotbird 13G satellite in November 2022 from Cape Canaveral, the EGNOS payload is ready to transmit the first EGNOS V3 test signals, as of Thursday, 1 June 2023. Placed in a geostationary orbit some 35,000 km away from the Earth, the payload underwent a rigorous testing phase before entering service. It is expected to have a life duration of 15 years.
"With the new payload in service, the EGNOS Space segment is now fully ready for the move to the next generation, EGNOS V3" said Jean-Marc Piéplu, EGNOS Exploitation Programme Manager at EUSPA. "Our role at EUSPA is to ensure the operability and the safety of the system with the core aim to benefit end users" he concluded.
Enhanced performance and increased autonomy for Europe
The next generation of EGNOS - EGNOS V3 - will augment both GPS and Galileo in the L1 and L5 bands. It is also set to provide additional satellite-based augmentation system (SBAS) service capabilities through a new SBAS channel on L5 and will deliver increased EGNOS service availability within and beyond the EU, supporting a growing number of users.
Aviation has benefitted greatly from EGNOS, namely from the system’s Safety of Life service. This has enabled better access to small and regional airports, increased safety and facilitated more sustainable flight routes across Europe.
Other transport means including maritime and rail also benefit from the EGNOS Safety of Life service. Thanks to its Open Service, EGNOS also increases the positioning accuracy for other land-based applications, notably precision farming, geomatics, and land management.

In addition to the improved user experience, the new EGNOS payload is another reaffirmation of the Union’s investment in advanced space technologies. Together with the EGNOS GEO-5 and with the deployment of the next generation Galileo satellites, Europe further increases its autonomous access to space.
EGNOS is Europe's regional satellite-based augmentation system (SBAS). It is currently used to improve the performance of GPS and will augment Galileo from 2025 onwards. EGNOS was deployed to provide safety of life navigation services to aviation, maritime and land-based users.
EGNOS uses GNSS measurements taken by reference stations deployed mainly across Europe and North Africa. These measurements are transferred to a central computing centre where differential corrections and integrity messages are calculated. These calculations are then broadcast over the covered area using geostationary satellites that serve as an augmentation, or overlay, to the original GNSS message.
The information provided by EGNOS improves the accuracy and reliability of GNSS positioning information while also providing a crucial integrity message. In addition, EGNOS also transmits an accurate time signal.
