EGNOS Service Provision, operations and evolution Seminar on Europe’s Satellite Navigation Programmes: Galileo and EGNOS

What is EGNOS about ?
2
European Geostationary Navigation Overlay Service:
• Provides services augmenting GPS signals:
• Better performance (accuracy, integrity, continuity, availability)
• Three services over Europe:
• Open Service (since 2010)
• Safety-of-Life (SoL) Service (since 2011)
• EDAS (EGNOS Data Access Service) (since 2012)
• Inter-operable with other regional systems:
• Operational: WAAS (USA), MSAS (Japan), GAGAN (India)
• Under study or development: Russia, South Korea, Australia, China, ASECNA (Africa)…
Will augment Galileo in 2025

relays error corrections to users
receive GPS data & send it to MCC
process GPS data to determine errors
uplink error corrections to EGNOS satellites

EGNOSSafety of Life services
NPA: Non-Precision Approach (2-D horizontal)
LNAV/VNAV: Lateral/Vertical Navigation Approach
LPV: Localiser Performance with Vertical guidance
CAT-I Category I Precision Approach (200 ft DH)
CAT-II Category II Precision Approach (100 ft DH)
CAT-III Category III Precision Approach (0-50 ft DH)
Tangible benefits for Aviation
• Access to airports in poor visibility conditions; reduced delays, diversions and cancellations
• New destinations: access to less congested airports with lower fees
• All weather operations for helicopters
Operational benefits
• EGNOS is a low cost alternative to an Instrument Landing System (ILS):
EGNOS LPV one-off cost ≈ 1 year of ILS maintenance
• Reduced fuel burn/costs and noise print
Reduced costs & environmental
impact
• Safest Aviation navigation standards made available to all flying vehicles in the whole European Airspace
Increased safety
