Presented at the 2014 ICCVE 3-7 Nov 2014, Vienna, Austria S3 summit session: Satellite navigation and positioning in a connected / automated vehicle environment

1. HOW SATELLITE NAVIGATION AND
CONNECTED VEHICLES ARE CONNECTED?

2. Is Global Satellite Navigation Systems
(GNSS) reliable enough?

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. What are the advantages?
makes the difference!
GPS
GPS + SBAS

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. Galileo is fully interoperable with GPS

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. How can Galileo benefit
connected vehicles?

•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. 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

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

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. 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
