Certification Process agreed with ERA
1. Trackside CCS and On Board Unit must be implemented according to the ERTMS Baseline 3 R2
standard and subject to certification. Regarding TRK ETCS, by not exporting application conditions
that affect interoperability to the OBU, the certification will be performed by a NOBO
2. The certification of the new on-board and trackside functions that include the introduction of GNSS
and the train integrity function will be carried out by a DeBO
All the products and functions of GNSS (including the Augmentation Network), which
are added to the provisions of point 1, will be used only for the purpose of improving
odometry by virtual balise and they are not impeding the line interoperability

Challenges
Track discrimination – At ETCS SoM (*)
The ERSAT-GGC track survey will help in the characterization of
the line in terms of suitability of the area for the VB location,
i.e.
Line green: VB can be placed even at small distances;
GNSS
Line red: we need different solutions
Open Sky
Frequent VBs increase performances through odometry reset
Reduce SR travelled distance at Start Of Mission
RFI is interested in the results of EU projects, as well as
technological and market trends (DCMF, Non GNSS Sensors,
Data Fusion) to extend current performances also in GNSS VB VB
denied zones. 1 2

12RFI «Smart Diagnostic» cofunded by from January 2020
Use Case Application
Integrated Systems for “Smart Maintenance”:
High reliability, real-time (short latency time), extensive territorial coverage, cybersecurity.
The application of 5G technology allows centralizing in real-time a huge amount of diagnostic information that can be
collected by sensors, installed wayside along the railway network.
Also, measurement systems installed on board RFI diagnostic trains can be centralized in real-time.
The integration of satellite technology with the terrestrial 5G network will maximize system performances, ensuring
high levels of service coverage and reliability.

17ERTMS on Trenitalia Regional Fleet, a long way to go..
First applications of ETCS on regional vehicles for new commercial service on the DD line Roma-Florence
E464 Vivalto E40X Semipilota Z1
Vehicle already ERTMS certified, currently in commercial service only on class B lines
New Regional Trains will be
progressively equipped with ETCS
following network installations
18Improvement of Low-Traffic Regional lines Management:
Satellite Technology introduction
Use of satellite technology (GPS, GLONASS,
EGNOS, GALILEO) in order to obtain:
A more reliable and available
speed/distance monitoring for train
positioning
Cost reduction to equip a line with
ERTMS system.
19An opportunity for Railway Undertakings: Integration with Satellite and
Virtual Balise
1. Increase in the Availability of the Balise detection chain of Signalling System
Now: unreliability of Signalling System due to failures of discrete onboard-inline interface (balises,
problems with the on-board antenna…..)
Real balise
detection
With ERSAT: The Virtual balise eliminates malfunctioning related to
the detection of the physical balises
RUs benefits: Virtual Real balise
detection: matching
• Savings in energy and time for unnecessary braking between GNSS
position and VBR
stored position
• Savings for time spent at starts of mission
20An opportunity for the Railway Undertakings (2): Satellite as an
additional speed sensor
2. Increase of reliability of Speed Monitoring of Signalling System
Now: Problems related to on-board odometry (slipping/sliding wheel), already
experienced in ERTMS
With ERSAT: Integration of satellite improve the accuracy of the odometry in condition of
low adhesion rail/wheel
RUs benefits:
• Savings in energy and time for unnecessary braking
• Savings for time spent at starts of mission
21An opportunity for the Railway Undertakings (3):
Multi-bearer TLC solution
3. Increase of reliability of Communication Network
Now: Problems due to weakness of interaction between onboard-trackside totally based
on GSM-R standard
With ERSAT: Using different bearers (GSM 3G/4G/5G mobile networks, Wi-Fi, Satellite)
links may be added or dropped as the train moves in or out of coverage without
interrupting the end-to-end connection.
22Trenitalia needs expected to be solved by ERTMS+SAT program in the long
term
1. Reduction of investment and maintenance costs.
2. Modernise signalling system at lower costs to ensure
sustainability, according to the European scale numbers.
3. Guarantee a real and long-term interoperable European standard.
4. Improve capacity of transportation networks extending ERTMS
system on secondary lines and urban nodes.
5. Minimize Impact on Operational Rules.
