The European Union's Global Navigation Satellite Systems Agency (GSA) has officially launched the EDG E project (Equipment for Dual frequency Galileo GPS and EGNOS) with a consortium led by Thales. This four-year project intends to develop a dual-frequency multi-constellation receiver, enabling enhanced navigation capabilities, support standardisation and certification preparation. The consortium includes Thales, Thales Alenia Space and ATR, as well as contributions from Dassault Aviation and the French Civil Aviation Authority (DGAC).

The GNSS receiver is the cornerstone of aircraft navigation systems. The system processes signals from satellite constellations and the Space Based Augmentation System (SBAS) to accurately determine aircraft position, altitude and velocity. The prototype receiver developed under the auspices of the EDG E project will use signals from US GPS and European Galileo positioning systems, as well as from SBAS multi-constellation EGNOS. The project aims to achieve a prototype demonstration by 2021. The prototype receiver performance will be evaluated during a flight test campaign performed by ATR using one of the company's test aircraft.

Initiated by the European Commission's Global Navigation Satellite Systems Agency (GSA), the EDG E project will support the launch of the Galileo satellite constellation.

Leading the EDG E project puts Thales at the forefront of the next generation receivers which will equip future aircraft by 2025, making navigation more precise and thus safer, unleashing the potential for increased air traffic.

EGNOS has been certified for use in aviation since February 2011, and is a very effective system to complement the US GPS, in order to provide better levels of performance, consequently enhancing aircraft approach capabilities. The next generation of EGNOS, called EGNOS V3, will further enhance performance by complementing both the EU Galileo and the US GPS satellite navigation constellations.

EGNOS v3 will provide aviation users with an increased quality of services, better accuracy and extended coverage area among other key performance indicators. Fundamental Element Programme is a medium that supports development of terminals and antennae fostering use of E-GNSS in all domains. In this perspective, EDG2E is an important step for GSA as it will contribute to availability of high technology products on the aviation market, taking benefit of Dual Frequency Multi Constellation feature offered by EGNOS v3.

At the end of the EDG E project, a new standard for GPS Galileo and SBAS aviation receivers will be completed, and the first SBAS dual-frequency GPS Galileo receivers for aviation will be ready for final development and provide safer operations not only for the aviation sector but also for other safety-critical applications.
