How connected are satellite navigation and connected vehicles?

  1. 1. HOW SATELLITE NAVIGATION AND CONNECTED VEHICLES ARE CONNECTED? Fiammetta Diani European GNSS Agency
  2. 2. Is Global Satellite Navigation Systems (GNSS) reliable enough?
  3. 3. First Europe’s contribution to satellite navigation: EGNOS satellite augmentation system The European GNSS Programmes 5 November, 2014 EGNOS  Augmentation system of GPS  Improves GPS accuracy  European coverage (but under extension in other regions, e.g. North Africa)  Available NOW, free of charge and widely available in automotive receivers Open Service (OS) Accuracy ~1m, free Available since October 2009 Safety of Life Service (SoL) Accuracy ~1m, compliant to aviation standards Available since March 2011 EGNOS Data Access Service (EDAS) Accuracy <1m, corrections provided by terrestrial networks Available since July 2012
  4. 4. What are the advantages? makes the difference! GPS GPS + SBAS
  5. 5. Second (and bigger) Europe’s contribution to satellite navigation: Galileo global system Galileo  Worldwide navigation system “made in EU”  Fully compatible with GPS  Initial operational services in 2015  Open service free of charge, delivering dual frequencies  Signal authentication will provide trustability Open Service (OS) Freely accessible service for positioning and timing Public Regulated Service (PRS) Encrypted service designed for greater robustness and higher availability Search and Rescue Service (SAR) Assists locating people in distress and confirms that help is on the way Commercial Service (CS) Delivers authentication and high accuracy services for commercial applications
  6. 6. Galileo is fully interoperable with GPS L5 L3 L1 L5 CDMA: Code Division Multiple Access Open signals Military/Governmental signals * future signal The European GNSS Programmes EU USA Russia Japan China India E6 E5a E5 E5b E1/L1 L5 L1 E6 L5 L1 E5b E6 L1 COMPASS IRNSS CDMA* CDMA* L5 CDMA since the design
  7. 7. Galileo will contribute to improved accuracy and position robustness  Multi-constellation: When buildings block the signal and reduce the number of visible satellites, the availability of more constellations ensures a much more accurate final position  Multi-frequency increases robustness of the position against jammers, because even if a satellite is not available or providing incorrect data, a reasonable accuracy will be achieved
  8. 8. How can Galileo benefit connected vehicles? Multi-constellation Galileo Authentication Multipath Resistant Data-less signal of Galileo *Source: “Experimental Results for the Multipath Performance of Galileo Signals Transmitted by GIOVE-A Satellite“, Andrew Simsky, DavidMertens, Jean-Marie Sleewaegen, Martin Hollreiser, and Massimo Crisci, Septentrio, ESA, 2008 **Source: “Estimating the Time-To-First-Fix for GNSS Signals Theory and Simulation Results”‘ Marco Anghileri, Matteo Paonni, Stefan Wallner, José-Ángel Ávila-Rodríguez, Bernd Eissfeller, Institute of Geodesy and Navigation, University FAF Munich, Germany’ 8 •Galileo in combination with other GNSS provides improved accuracy, availability and allows for a faster time-to-first-fix* • Galileo is expected to be the only GNSS providing Open Service authentication, a “digital signature” to ensure no-spoofing •The strength of Galileo signal, together with an advanced code modulations, makes Galileo better mitigating multipath effects (especially in E5, but also E1)** • Using the data-less signal with a 100ms length for the secondary code, Galileo allows for an enhanced indoor penetration, improved performances in urban canyon, better performances in noise measurements and improved sensitivity in A-GNSS mode Enhancement of currently offered services Development of new value-added services
  9. 9. Road GNSS receivers already include satellite augmentation and multi-constellation  Satellite Based Augmentation Systems (e.g. EGNOS) capability is commonplace in today’s receivers  Extra accuracy when you need it at no cost  Level of confidence of GPS signal  Multi-constellation (e.g. GPS/Galileo/Glonass) is rapidly becoming the baseline:  Much improved robustness and performance for users SatNav capability of Road devices* *Source: GSA analysis on GPS World Survey 2013 Percentages based on number of models available, not sales
  10. 10. A civil system with priority on users: European GNSS Service Centre Website Provide information to users and capture user’s feedback  Static content: general system and services information  Dynamic content: including scheduled maintenance activities Customer interaction functionality  Helpdesk ticket management  Skilled people  User’s database population  Procedures involving all actors GSA is setting a preliminary Customer assistance Photo: INTA
  11. 11. Results from R&D projects funded under European Seventh Framework Programme CoVel- Lane-level road navigation with EGNOS In-vehicle device which enables lane-level traffic management in urban areas, broadcast EGNOS data to vehicles and combining V2V and V2I communication systems
  12. 12. Results from R&D projects funded under European Seventh Framework Programme GAIN- Galileo for Interactive Driving  Solution for detecting and mitigating multipath in urban areas  Enhanced Active Green Driving demonstrated in real scenarios: • Roundabout: The vehicles velocity is adapted to the distance and geometry automatically • Crosswalk: The speed will be reduced to make the driver aware of approaching a pedestrian crossing • Ecological Driving: The vehicle adopts the optimal velocity under consideration of the traffic ahead and all information via C2X communication
