EGNOS for ITS: an option now, paving the way for Galileo

9 June 2011 – GINA @ ITS Lyon

Early 2009

EGNOS not known in Road sector

Very few EGNOS enabled automotive receivers

Early 2011

Leading service and technology providers acknowledge EGNOS

Early adopters in dangerous goods and in road pricing

An exhaustive study from EC and many trial results from FP7

Most automotive receivers are EGNOS enabled

A long distance travelled at high speed…

EGNOS increased accuracy

EGNOS provides a better accuracy, specially in open sky scenarios, as highways (now proven in different FP7 trials)

The technology proposed by the consortium selected for negotiation in the French ECOTAX (*) is EGNOS enabled

Early Adopters

Position errors much smaller 3m position error (at 95%) with

EGNOS. EGNOS provides substantial

accuracy improvement in “highway” environment

(*) currently suspended for redress procedure

EGNOS integrity

Operators (toll chargers, EETS, public authorities, logistic operators) have an increasing need to provide a guarantee of positioning

EGNOS integrity can be used to obtain a confidence level in the position

Potential applications: GNSS-based road pricing schemes (to prevent or manage claims), dangerous goods transport

Leading oil & gas company ENI is implementing EGNOS on all the fleet (1,500 trucks) and is experimenting the integrity in operational way.

Early Adopters

EGNOS 2 ROAD project

EC - DG ENTR (Galileo) "Assessment of the utilisation of EGNOS in the road transport domain “

Objective: to assess the added value/ benefits of GPS + EGNOS compare to GPS-only for the business in the road sector

Focus: Comparison to GPS of

EGNOS Open Service EDAS

Two road applications: Road tolling Tracking & tracing of professional fleets

Two operational cases/ environments : Extra-urban (A12 Società Autostrada Tirrenica) Urban (Roma Servizi per la Mobilità)

Trial campaigns - small car

GPS/INS IMU for true pathCase: unique antenna

Case: standard antennas

4 T-Box OBEs (2 * GPS, GPS + EGNOS)

Examples of test configurations - Motorway

Roma Via di Monserrato

Example of test configuration in Roma

Roma Via di Ripetta

Roma Via di Panico

Types of applications in Roma

Applications:• Limited Traffic Zones• Tracking and tracing of tourist coaches• Management of parking places for coaches• Tracking and tracing of public transport• City logistics• Urban pricing schemes

Added values of EGNOS / EDAS• Accuracy• Availability• Position guarantee (protection level provided by the horizontal integrity)• Vertical protection level

‘It’s there, use it’

Criteria:• Launch new applications

(Road pricing in Roma ?)• Increase addressable

volume and penetration• Less frauds and claims• Lower costs to levy fees
