  1. 1. ITN - Infrastructure, Telematics and Navigation Turin – Lingotto FIERE 15 October 2009 Ing. Mario Caporale 1
  2. 2. Satellite Systems are involved in many applications Navigation Data Relay Satellite Telecomunication Earth Observation Sats Processing Mobile Centre End Users Decision Units Centres Aerial Observation Center ETS unit IMINT Earth Stations Network mediation Images Fixed and Mobile Data User Acquisition Sensors reception Community Data Acquisition Data Exchange Data Distribution 2
  3. 3. Satellite Navigation Systems contribution • A system that is central to the lives of millions of civil and commercial users • Public safety dispatch – improves response time • Search and Rescue – locates emergency calls • Air Traffic Control – guides planes in all weather • Telecommunications – primary timing source, • Transportation – tracks trains, trucks, vital shipments • Underpins Safety and Security 3
  4. 4. The European GNSS EGNOS is the first European contribution to GNSS to provide civil complement to GPS over larger European area, interoperable with WAAS(USA) and MSAS(Japan). GALILEO is the Autonomous European GNSS system •Global coverage •30 satellites •Independent but interoperable 4
  5. 5. Galileo Signals and Services E5a E5b E6a E6b,c E1b,c E1a E 5 a E 5 b E 6 a E 6 b , c E 1 a E 1 b , c Open Service (OS) Single frequency Dual frequency Commercial Service (CS) Value added Multiple Carrier Safety-of-Life Service (SoL) Public Regulated Service (PRS) Search and Rescue Service Near real-time; Precise; Return link feasible 5
  6. 6. The new capabilities introduced by Galileo The European GALILEO system introduces new capabilites: Signal Integrity Service Guarantee Signal diversity Certification for the Service “Safety of Life” Local Elements Increasing the Availability: – GPS alone: 55% of urban coverage – GPS + Galileo: 95% of urban coverage 6
  7. 7. GNSS & Road Sector GNSS Technology • Present GPS commercial (mass market) utilisation has an accuracy of ~15m • European EGNOS augmentation ~4m • Concerted action with Wireless communication links (GSM, UMTS, WiMAX, Satcom) and IT platforms enable a wide range of innovative services (Pay as You drive, Location Based Services, Traffic monitoring…) 7
  8. 8. Impact of New Satellite Positioning Systems on ITS Road Tolling Important role of satellite positioning and cellular communications in road charging interoperability Expected benefit of new satellite positioning systems: Possibility to define zone tolls Possibility to charge according to route followed and time of the day Precise positioning allows high rate discrimination between toll zones Higher reliability allows lower rate of errors, i.e. fair charging, lower rate of contentions Car Insurance 8
  9. 9. Impact of New Satellite Positioning Systems on ITS Emergency Calls Impact of increased performance of positioning technology: Vehicle Higher performance Airbag status Wheels status ABS positioning may allow: Vehicle sensors Gyrometer No of passengers Vehicle ID E-Call • Lane of accident detection .... GSM GPRS E-Call Service Centre GPS module or UMTS • Identification of specific Navigation unit Localisation conditions (e.g. turning, Medical rescue hump, deep) Emergency button Mechinal rescue Police assistance X-112 ... E-112 fallback …and: E-Call Service Centre • Reduce wrong positioning on PSAP X-112 parallel roads • Reduce time to move emergency vehicles on the spot 9
  10. 10. Impact of New Satellite Positioning Systems on ITS Dynamic Navigation Impact of increased performance of positioning technology: Improved availability = Reduced reliance on in- vehicle inertial sensors: Low cost entry-level navigation systems Door-to-door PDA based systems with acceptable performances also when pedestrian Improved accuracy = More robust navigation service: No wrong positioning on parallel roads 10
  11. 11. Impact of New Satellite Positioning Systems on ITS Hazardous Goods Transport Expected benefit of new satellite positioning systems: Improved positioning availability, reliability, accuracy = more safety in the transport Reduced time to the spot for emergency vehicles Better prevention/management of intersections of hazardous goods transports Monitoring in difficult environment (tunnels, mountains …) 11
  12. 12. Impact of New Satellite Positioning Systems on ITS Access Control Present technology based either on: • Automatic Number Plate Recognition (ANPR) • e.g. “Ecopass” for Milan dowtown or • Dedicated short-range communications (DSRC) • e.g. “Telepass” devices operating on the Italian highways networks 12
  13. 13. Impact of New Satellite Positioning Systems on ITS Access Control So liability critical application will be possible with GALILEO. Quick definition But which benefits come from the use of GNSS in Access Control applications? of access controlled areas for emergency operations Dynamic definitions (SW) of Access controlled areas 13
  14. 14. Impact of New Satellite Positioning Systems on ITS Law Enforcement Liability critical Applications need law enforcement activities *System could provide automatic law enforcement but citizen acceptance would be terribly low Electronic Number Plate (ENP) starting from the present governamental initiatives A hand held device dedicated to the enforcement operators can potentially obtain: •Static info: vehicle owner, number plate, engine type… •Dynamic info: status of insurance and fees… •Instantaneous info: present driver, authorisations… 14
  15. 15. Impact of New Satellite Positioning Systems on ITS ADAS (Advanced Driver Assistance Systems) The more challenging ADAS applications require positioning performances (radio positioning + map) not met by current systems EGNOS/Galileo will probably be enablers In some cases even EGNOS/Galileo are not sufficient = local element? EGNOS/Galileo can also have a role in improving map accuracy In safety-related applications the availability of integrity information will be essential 15
  16. 16. National Projects on ITS Italy, recognising the potentiality of SatNav technology as powerful “enabler” of applications and services, have undertaken initiatives to develop pre-operational projects to pave the way to an extensive use of European GNSS. The national projects, aimed to exploit the new features GALILEO will bring, answer to a specific public demand: Increase the Safety in the Transport Sectors (Maritme, Civil Aviation, Road Transport and infomobility) and in general Improve Territory Safety and Security The national projects on ITS are concentrated to: – Hazardous goods transportation – Road Traffic and Infomobility 16
