  1. European GNSS for ITS: EGNOS contribution ITS WORLD CONGRESS 2011 Orlando– 18 October 2011

  2. Few words on European GNSS What is EGNOS? EGNOS 2 ROAD Findings Conclusions

  3. The European GNSS • Global Navigation System • Initial Operational Capability, from 2014 will provide: • - Open service • Public Regulated Service • Search and Rescue Service • And permit to experiment: • Commercial Service • Safety of life Service • FIRST LAUNCH 20/10/2011 Satellite Based Augmentation System Open Service: operational since October 2009 Safety of Life service: operational since March 2011 EDAS: ground distribution of EGNOS corrections (experimental service) European coverage, under extension in other regions

  4. The European GNSS Agency Public European organisation, shared by European Commission and the 27 Member States • Preparing the Market for European • Satellite Navigation Systems (EGNOS and Galileo): • Market knowledge • Research and Development • Co-marketing and support to early adopters

  5. Few words on European GNSS What is EGNOS? EGNOS 2 ROAD Findings Conclusions

  6. What is EGNOS? 6 NavigationLand EarthStations GPS signals 34 Ranging & Integrity MonitoringStations (RIMS) EGNOSService Area 2 Support Facilities 3 GEOSatellites 4 MissionControlCentres EGNOS Satellite Footprints

  7. What is provided by EGNOS? GPS SBAS (EGNOS) • EGNOS Open Signal added value •  enhanced accuracy in the position • EGNOS Commercial Serivce/EDAS added value • higher availability of the enhanced accuracy • qualification/ confidence in the position (so called “protection level”)

  8. 0 Availability of EGNOS for Road applications 2011 • Leading service and technology providers start knowing EGNOS • Early adopters in dangerous goods • An exhaustive project from EC and trial results from R&D • Most automotive receivers are EGNOS enabled 2009 • EGNOS not known in Road sector • Very few EGNOS enabled automotive receivers

  9. Few words on European GNSS What is EGNOS? EGNOS 2 ROAD Findings Conclusions

  10. EGNOS 2 road Project EGNOS2road project was run to provide a technical and economical evaluation of the use of EGNOS/ Galileo wrt GPS for two road extra-urban and urban applications: • Road charging • Tracking & tracing of professional fleets EGNOS2road has been funded by the European Commission • The project has been finalised in August 2011 • The results are being presented now to major stakeholders

  11. Business cases Extra-urban business cases: • Road charging • Tracking & tracing of third-party service fleets Urban business cases: • Tracking & tracing of touristic coaches • Tracking & tracing/ monitoring of access/ circulation in Limited Traffic Zone (LTZ) • Tracking & tracing of Local Public Transport fleets operated by a Service Provider • Management and monitoring of vehicles for goods delivery in a large urban area, according to the local regulation • Involvement of two road operators: • Extra-urban/ Società Autostrada Tirrenica • Urban/ City of Rome

  12. Trial campaign (1/3) • Conducted along extra-urban and urban road networks/ driving environments/ critical and interesting stretches • Using EGNOS-ready technology available on the market: • GPS/EGNOS off-the-shelf receivers and antennas • Commercial device for the automotive markets • Proven solution EGNOS CS/EDAS enabled

  13. Trial campaign (2/3) • Different types of GPS/EGNOS receivers/ antennas • Different types of vehicles

  14. Trial campaign (3/3) • Different critical points and interesting stretches Intersection Close/ parallel roads Ramp LTZ gate

  15. EGNOS msg Positions and raw data Value-Added Service Provider Corrected positions and Protection level EGNOS CS/EDAS processing • Measurements of: • Accuracy of the position wrt to a reference trajectory (true path) • “Protection level” providing the qualification/ level of confidence in the position (thanks to the processing of EGNOS integrity)

  16. EGNOS performances wrt GPS EGNOS OS and EGNOS CS/EDAS key performance values (average) for horizontal accuracy and protection level EGNOS OS higher accuracy wrt GPS EGNOS CS/EDAS  higher accuracy wrt GPS + qualification/ confidence on the position Extra-urban environments Urban environments Extra-urban environments Urban environments Number of positions for EGNOS CS/EDAS processing

  17. EGNOS added value in extra-urban roads True path  Enhanced accuracy and “protection level” provided with EGNOS allow to: • Distinguish two close/ parallel roads of different networks, typically tolled and not-tolled stretches (e.g. motorway very close and parallel to secondary lane, motorway and secondary lane crossing each other) • Distinguish the position of the vehicle just after/ before a motorway intersection or ramp near the gates

  18. EGNOS added value in urban roads True path  Enhanced accuracy and “protection level” provided with EGNOS allow to: • Distinguish close/ parallel roads in various LTZ areas where different rules/ pricing schemes are applied • Distinguish roads in dense urban areas inside/ outside the LTZ areas • Monitor in real-time vehicles itineraries and stops, in line with permits • Have a reliable positioning of urban regulated fleets

  19. Few words on European GNSS What is EGNOS? EGNOS 2 ROAD Findings Conclusions

  20. Summary of EGNOS 2 ROAD Key findings Positive feedbacks on EGNOS use from both road operators: EGNOS OS added value is the enhanced accuracy at zero costs in new systems EGNOS Open Signal is recommended in new systems for all extra-urban and urban business cases EGNOS CS/EDAS added value is the enhanced accuracy and guarantee/ qualification, that has the potential to: • bring economical benefits • give service robustness for starting a type approval (i.e. legal use) EGNOS CS/EDAS enabled solutions are proven for road applications and ready to use. EGNOS CS/EDAS economical benefits depend on the business case (e.g. network extension, number of vehicles, etc.)

  21. Manufacturers are already ensuring that their products are ‘Galileo ready’ • Galileo is interoperable with GPS • Together they will offer enhanced accuracy and availability of position in the urban environment • Galileo will reach Initial Operating Capability (IOC) 2014/15 • 18 new satellites will already offer much benefit • The Open Service (OS) Interface Control Document (ICD) was published in 2010 • New receivers being purchased today need to be future proofed and made ready for the availability of Galileo in just a few years
