Airport mobiles surveillance and controlby means of EGNOS METIS Workshop Benefits of EGNOS in Civil Aviation Istanbul 18 November 2009 • Pierre GRUYER • Email: gruyer@m3systems.net
Agenda • Context & Objectives • Description & Key features • EGNOS added value & performances • Key enablers & lessons learnt METIS Workshop Benefits of EGNOS in Civil Aviation, Istanbul 18 November 2009
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 radarsor GNSS solutions(EGNOS/GALILEO) METIS Workshop Benefits of EGNOS in Civil Aviation, Istanbul 18 November 2009
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.

Description Airport mobiles surveillance and control by means of EGNOS • high accuracy and integrity of position • Improvement of safety and efficiency Wireless network Location: “Mohammed V” Airport of Casablanca (Morocco) One ground supervision station 1 equipped vehicle Supervisor Driver Detection of conflicts Navigation aids & Warning equipped vehicle location METIS Workshop Benefits of EGNOS in Civil Aviation, Istanbul 18 November 2009
Key features : Navigation & Warning alarms • On board services: • Navigation services: vehicles position on airport map • Control service: alerts displayed on driver HMI in runway incursion METIS Workshop Benefits of EGNOS in Civil Aviation, Istanbul 18 November 2009
Key features : Ground supervision • On ground services: • Control service: alerts displayed on supervisor screen in case runway incursion • Decision Support service: real-time information (location, speed) about equipped vehicles.

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.

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 METIS Workshop Benefits of EGNOS in Civil Aviation, Istanbul 18 November 2009
