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)

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
