EGNOS System ArchitectureEGNOS is an SBAS that “augments” the signal of satellite positioning systems e.g. GPS, GALILEO, GLONASS
INMARSAT AOR-E (15.5°W), ARTEMIS (21.3°E), INMARSAT IOR-W (25°E)

EGNOS Service Area
EGNOS is delivering a free open service over Europe since October 2009. It will deliver its services for at least > 20 yearsEGNOS satellites footprint cover also Africa.

Technical feasibility and users’ interest
Temporary EGNOS reference stations installed in several African countries: Chad, Cameroon, Central African Republic, Congo, Ethiopia, Kenya, Zambia, Namibia and South Africa; flight testing took place during a East-to-West flight from Dakar to Mombasa on 19-20 May 2005
A demonstration of the use of EGNOS for advanced rail traffic management, on low-density rail lines, Gauteng, South Africa 2005
Allows for IFR-like operation in non ILS-equipped airports Increase in airports capacityIncrease in safetyIncrease in flight capability (e.g. helicopters)Expensive land based navaids can be avoidedEnables their long term decommissioning => lower terminal charges
General operational benefits
Reduction in angle of approach (direct and curved)Better lateral guidance
EGNOS enables a reduction in the decision height
EGNOS benefits in aviation
Impact on Economic development and integration
37 % from Africa is 250km from an ILS equipped airport
87 % from Africa is 250km from a main or regional airport
EGNOSpotential
Use of EGNOS for land management
Hydrographic survey
Crustal deformation monitoringLandslides, flooding, volcanic crustal dynamics, etc
Improvement of National Geodetic Network
Cartography, cadastre and GIS data collectionUpdate of regional technical map, standardised cadastral surveying, georeferencing orthoimages satellite images, etc.
Structure monitoringBridges, dams, buildings
Civil Engineering
Support to meteorological analysis and forecasts
EGNOS benefits in Africa
Economic opening-up of isolated regions, reduction of access costs to regional centres
Improving transport infrastructure at once by making regional airports accessible to nationally and internationally
Reducing maintenance costs, safety and security of railways
Improving dramatically air and maritime transport safety
Impacting positively agriculture, mining, energy, and land management
Reduction of costs, increased safety and greater reactivity for humanitarian interventions
Building African capacity at managing large projects
Establishing pan-African infrastructure
Training of African users and operators
Reinforcement of African academic institutions
Results of a Cost-benefits analysis
