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

27 March 2019, Vilnius

Silvia Porfili, EGNOS Service Design Engineer, GSA

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

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
