2 EUROPE’S FIRST STEPS ESA began research and development in cooperation with the EC and the civil aviation community. The development strategy was conceived with two major pillars: EGNOS (European Geostationary Navigation Overlay Service) A pan-European “augmentation system”, complementing GPS to deliver reliability information to users Today, EGNOS is operational and certified, forming the basis of a wide range of general and safety-critical applications across our continent. GALILEO A fully autonomous and interoperable worldwide satellite navigation system, broadcasting global navigation signals for high-performance services.

GALILEO SATELLITE: Avere ruolo di 'Prime Contractor' del Galileo Satellite sul prossimo Batch 3 SISTEMA: Mantenere il ruolo di System support a ESA, inclusi piattaforme e tools EGNOS Mantenere il ruolo industriale su RIMS \ ricevitori, Centrali di controllo di missione La navigazione satellitare è, e rimarrà, in evoluzione continua, sia di contenuti che di contesto. Per il settore industriale, risulta indispensabile, alla pari di quanto sta avvenendo in altri grandi paesi: Che siano attivati progetti nazionali di Ricerca e Sviluppo, a supporto Che sia ancor più incrementato il supporto Istituzionale sui tavoli europei
