EGNOS (European Geostationary Navigation Overlay System), which monitors the performance of the existing GPS and Glonass systems and reports to users on their performance, continued to receive TEN-T support in its critical design phase, while the ESTB (EGNOS System Test Bed) has been providing a real EGNOS space signal since February 2000.
Le projet EGNOS (European Geostationary Navigation Overlay System), qui surveille la performance des systèmes GPS et Glonass existants et en informe les utilisateurs, a continué à bénéficier d'un concours financier RTE-T au cours de la phase critique de la conception, tandis que le banc d'essai ESTB (EGNOS System Test Bed) émet depuis février 2000 un signal spatial EGNOS réel.
