1 Roma, 22 January 2016 GNSS technology advantages in a multiconstellation framework Authorisation of placing in service in the context of new technologies

2 Assumption For its size and complexity, the rail system has been split into structural and functional subsystems (Directive 57/2008 /EC). Among the structural subsystems, the control-command and signalling subsystem includes all the necessary equipments (trackside and on-board) to ensure safety and to command and control movements of trains authorized to travel on the network. 2

3 Assumption The European Rail Traffic Management System (ERTMS) is the interoperable European control-command and signalling system. ERTMS, unlike the national systems, can be applied over the entire European rail network, regardless of the of traffic control logics applied by the infrastructure managers. The implementation of ERTMS on the existing rail networks based on (old) electromechanical technologies involves huge investments 3

4 ERSAT Project Goals WHAT To ensure a development of ERTMS that: preserves system interoperability preserves the safety levels achieved in the consolidated applications offers to the market of local and regional networks ERTMS solutions at lower costs HOW To integrate ERTMS devices with technology belonging to other sectors: Satellite Commercial GSM 4

5 ESRAT: operators involved Ansaldo STS: responsible for satellite projects for railway CCS Rete Ferroviaria Italiana: infrtastructure manager Bureau Veritas: indipendent safety assessor ANSF: national railway safety autority and with the contribution of the Italian and European Space Agencies 5

6 Application framework ERTMS Livello 2 6

7 Scenario Replacing of Eurobalise with Virtual Balise Group Eurobalise 7

8 Scenario Replacing the GSM-R network with a system that aggregates cellular networks of the various commercial operators and satellite network. SATELLITE RBC GSM-2 Router GSM-1 Public TLC Network 8

9 Authorization procedure: roles and responsibilities Regulatory framework: o Safety and Interoperability Directives o Regulation UE 402/2013 (CSM RA) o Technical Specifications for Interoperability Operators involved: o Applicant/Proposer o Nobo(s)/DeBo(s)/CSM Assessor(s) o National Safety Authority 9

10 Challenges Technological: Integration into the rail system of technology belonging to other sectors RAMS requirements QoS Process: Recognition and integration of certifications issued by other sectors Need to update the reference standards Legal/Contractual: Roles and responsibilities : maintenance, service provider 10

11 Challenges: details and questions Could the authorization process be based on the current procedures? There is the need to define the criteria (based on processes already applied in the aeronautics framework and blessed by ERA) through which it s possible to state that the process related to the implementation and management of the service complies with the system s essential requirements Some features of the system are associated with processes and applications outside the railway system: are these processes and applications safety critical? If yes, there will be safety requirements exported to processes and applications outside the railway system: such interface must be defined SIL requirements must be specified 11

12 Challenges: details and questions The processes applied to ensure compliance with the SIL requirements must be comparable to those of the railway sector To be agreed with ERA To be included in the CCS TSI? It must be assessed whether the processes applied in the event of modifications to the system could be traced to the process of risk management applied in the railway framework Definition of the system configuration management 12

13 Challenges: details and questions For requirements with an impact on the availability of the system, minimum reference values of availability should be defined To be agreed with ERA What constraints may result from different operating rules applicable in different Member States? What documents does ERA expect to issue its approval? 13
