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

                                                                                                                8

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.

Improvement 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.

                                                                             19
An 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
                                                                                                           20
An 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

                                                                                                21
An 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.

                                                                                        22
Trenitalia 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.

                                                                                              23
