EGNOS2road:
EGNOS services and Galileo Authentication for road
2 Context
EGNOS2road project was run to provide a technical and economicalevaluation of the use of EGNOS/ Galileo wrt GPS for two road extra‐urban and urban applications:
– Road charging
– Tracking & tracing of professional fleets
EGNOS2road evaluation was elaborated on the basis of:
– Technical analysis built on extensive trials in operational conditions, different road environments
– Assessment of operational benefits in selected real business cases
– Economical quantification through concrete business plans
– Identification of the necessary elements for legal value/ regulated use
3 EGNOS/Galileo services added values
EGNOS OS added value
enhanced accuracy in the position / capability to give a value for the position nearer to the true position (i.e. minor error in the position measurement)
EGNOS CS/EDAS added value
capability to enable the implementation of solution, providing higher availability of the enhanced accuracy (thanks to the distribution of EGNOS data via alternative means wrt SiS) and qualification/ confidence in the position (thanks to the integrity processing)
Galileo Authentication added value
capability to provide a more trustable source of the position (i.e. inhibition of meaconing and spoofing effects ‐ not jamming)
4 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 LTZ zones Tracking & tracing of LTP fleets operated by a LTP Service Provider Tracking & tracing/ monitoring of vehicles for goods delivery,
according to the regulation
Involvement of two road operators: Extra‐urban/ Società Autostrada Tirrenica Urban/ City of Rome
5 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 antennasCommercial device for the automotive marketsProven solution EGNOS CS/EDAS enabled
6 Trial campaign (2/3)
Different types of GPS/EGNOS receivers/ antennas Different types of vehicles
7 Trial campaign (3/3)
Different critical points and interesting stretches
Close/ parallel roads Intersection Ramp
LTZ gate

EGNOS msg
Positions and raw data
Corrected positions and Protection level
Measurements of:Horizontal 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)
9 EGNOS performances wrt GPS (1/2)
EGNOS OS enhances position accuracy wrt GPS: Accuracy improvement wrt GPS ranges from 0,1 m to 3,7 m (on average, also in case of dense tall buildings/ foliage conditions/ urban roads)
EGNOS CS/EDAS further enhances position accuracy wrt GPS and provides level of guarantee of position/ capability to qualify position data:Horizontal accuracy improvement wrt GPS ranges from 0,1 m to 4 m (on average, also in case of dense tall buildings/ foliage conditions/ urban roads)“Protection level”

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

11EGNOS 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
12EGNOS 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 areasMonitor in real‐time vehicles itineraries and stops, in line with permitsHave a reliable positioning of urban regulated fleets
13EGNOS opportunitiesin extra‐urban business cases
EGNOS OS:–Road charging
–Tracking & tracing of third‐party service fleets
EGNOS CS/EDAS:Road charging
Added value is the enhanced accuracy
Zero costs in new systems
EGNOS OS suggested in new GNSS systems
Added value: enhanced accuracy and guarantee/ qualification of position
Potential to bring economical benefits (i.e. willingness to pay) generated by claims reduction
Possibly interesting for an ETC Service Provider
14EGNOS opportunitiesin urban business cases (1/2)
EGNOS OS:–Tracking & tracing of touristic coaches
–Tracking & tracing/ monitoring of access/ circulation in LTZ zones
–Tracking & tracing of LTP fleets
–Tracking & tracing/ monitoring of vehicles for goods delivery
Added value is the enhanced accuracy
Zero costs in new systems
EGNOS OS suggested in new GNSS systems
For the LTP fleets, RSM is also evaluating its adoption in “ready”systems

EGNOS CS/EDAS:–Tracking & tracing of touristic coaches
–Tracking & tracing/ monitoring of access/ circulation in LTZ zones
–Tracking & tracing/ monitoring of vehicles for goods delivery
–Tracking & tracing of LTP fleets
Added value: enhanced accuracy and guarantee/ qualification of position
Potential for a regulated use that brings economical benefits (i.e. willingness to pay) generated by revenues increase (thanks to new subscribers and correct behaviour of present subscribers, claims reduction and efficient personnel operations, social benefits)
Regulated use requiring type approval for legal value
Position guarantee perceived interesting value by RSM, enabling to qualify position data from the different LTP Service Providers

16Key findings on EGNOS use for road (1/2)
Positive feedbacks on EGNOS use from road operators:
EGNOS OS added value is the enhanced accuracy at zero costs in newsystems EGNOS OS suggested in new GNSS 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 (i.e. willingness to pay)give service robustness for starting a type approval (i.e. legal use)
The legal value/ regulated use requires a type approval, as for any other technology
EGNOS CS/EDAS enabled solutions proven for road applications ready and easy to use
17Key findings on EGNOS use for road (2/2)
EGNOS CS/EDAS economical benefits depend on the business case

18Key findings on Galileo Authentication opportunities for roadMainly in extra‐urban business cases
Galileo Authentication:
Alone gives the capability to reduce frauds only for third‐party fleet monitoring (e.g. extra‐urban tracking & tracing of third‐party service fleet)
Combined with EGNOS CS/EDAS gives a more robust position so thatto reduce claims and frauds (allowing to substitute the OBE sensors functions of present GPS‐based solution)
