Context

The growth of air traffic complicates the management of the surface
movements:
· “See and be seen” principle for surveillance & control is a key factor
· Bad meteorological conditions or low visibility (LV): airport stakeholders have
little or no knowledge of ground surface traffic
· Emergency situations: surveillance, control and management of vehicles are
critical
 Risks of collisions & incursions into dangerous & restricted areas (e.g runway)
Congestion of airport areas

Identified solutions: A-SMCGS (Advanced Surfaced Movement Guidance
and Control Systems) provide accurate positioning and surveillance
services, based on surface radars or GNSS solutions
(EGNOS/GALILEO)

Objectives

Demonstrate a subset of A-SMGCS applications providing surveillance and
conflict detection services to operators and vehicle drivers using EGNOS
and wireless technologies.

Assess EGNOS coverage & validate operational use in Casablanca airport.

Show the benefits of using EGNOS aware applications for the monitoring of
moving airport assets thanks to the Demonstration.

EGNOS added value : Errors correction & Integrity
 EGNOS uses the same frequences as GPS satellites
 unique receiver and antenna for GPS and EGNOS reception
 EGNOS enables :
•GPS errors correction for better accuracy
•Integrity risk monitoring
SAFE DRIVE provides an integrity risk based on EGNOS signal processing :
% of chance to have a precision inferior to 6m.

EGNOS measured performances (C/N)
Example of shadowing & multipath effects near buildings
Performances on the runway (clear environment)
C/N <35dB
35dB < C/N < 38dB
38dB < C/N
C/N: Carrier to Noise ratio

Key enablers & lessons learnt in Casablanca
 EGNOS messages processing
•GPS errors correction
•XPL computation
 EGNOS signal available in Casablanca
 RIMS stations monitoring GPS signals and ionospheric propagation in
the area
 New RIMS station are needed to cover North Africa
 Airport map providers and certification
 EGNOS accuracy is useless if the map is wrong!
 Datalink subnets covering all the airport surface
 UHF is advised (and perhaps WiMax for the future…)
 A-SMGCS solution deployment
 ICAO/Eurocontrol commitment is needed in order to give the rules
