ERTMS Evolution: the role of satellite

ARTES Applications Workshop 2016 Chiel Spaans, ERA ERTMS Unit

Overview

1. EU context

2. ERTMS

3. Evolution of Railway Radio

4. Role of Satellite

5. Conclusions

2

EU railway policy

Opening of the railway service market Different roles for

Infrastructure Managers and Railway Undertakings

Competition between Railway Undertakings

3

Opening of the railway products market Technical compatibility EU wide authorisations Competition between suppliers

Interoperability Uninterrupted movement of trains Maintaining the high safety level of railways Harmonisation of parameters Standardisation Lower costs

Role of the European Railway Agency

• European Railway Agency (ERA), Valenciennes (F) • established 2004/2005, approx. 155 staff • core domains: Interoperability, Safety, ERTMS**

* Technical Specification for Interoperability **European Rail Traffic Management System (the harmonised control-command and signalling system)

ERTMS

ERTMS: European Railway Traffic Management System

Mandatory for new or upgraded infra and trains

ETCS: European Train Control System: train protection system Providing safe headway to trains Monitors train speed and position as well as trackside status Allowed speed information to driver Automatic braking when needed

GSM-R: GSM for Railways

Train-to-track datacommunication for ETCS Operational voice communication, e.g. driver – traffic control Non-operational voice and data communication

ETCS rollout ongoing

GSM-R in operation since 2000, end of support expected after 2030

Operational in Europe, Asia, Australia, Middle East

ERA Program on Evolution of Railway Radio

Concluded by the European Commission (in 2013):

2030: Risk of obsolescence of GSM-R 2018: The new system has to be defined 2022: The new system has to be available for deployment

ERA – as ERTMS system authority – is tasked to lead the program and has to

deliver proposals for the update of the legal documents (CCS TSI).

ERA coordinates the activities/deliverables in the workstreams: Functionality Architecture/technology: satcom to be included? Spectrum Migration

Contributors:

Railway sector (train operators, infra managers, UIC, UNISIG, etc.) ETSI (users, supply industry, etc.) Research programs (e.g. Shift 2Rail)

Overall Scope of work

Workstreams Functionality:

Mandatory requirements (application approach) with relevance for CCS TSI (to be supported by GSM-R and new technology during migration)

Additional requirements, without relevance for CCS TSI Remove what’s not needed/prevent cost drivers

Technology/architecture: IP based communication, 3GPP “family”, other technologies (wifi/satcom) to be

investigated, limited “catalog” Technical co-operation with GSM-R is essential Separation of application layer and communication bearer (OTT?) Clear definition of interfaces Onboard - Trackside

Spectrum: Investigate re-use of current railway spectrum Check possibilities for additional spectrum (dedicated, shared) Analyse and influence EU and national spectrum policy

Migration: Operational co-existence of GSM-R and other technologies Identification of drivers for deployment of new functions/technology/architecture Economic Impact analysis of different migration scenarios

Can ERTMS benefit from satellite?

General: possible cost reduction

Conditions/challenges for introduction in CCS TSI

Based upon standards (no proprietary solutions) Sustainable (long term support)

Satellite based localisation: some examples

Virtual balise for ETCS Level crossing

Satellite based communication?

Integration with terrestrial systems, IP based Suitable for operational voice and (ETCS) data Current technology/systems or wait for 5G? Implementation/migration issues

Satcom feasibility study

ERA study on feasibility of satcom

In cooperation with ESA Draft conclusions end of 2016

Topics to be analysed:

Identification of technical/functional parameters and criteria Overview of the current satcom market and (near) future

developments Analysis and assessment: technical, functional, geographical

scope, economical impact Conditions for successful implementation

Results of the study will be included in the system architecture

report (early 2017)

Need for further investigation Additional studies/research (ESA)

10

Conclusion

Strong interest of ERA in research related to the use of satellite localisation and

communication

Investigation of feasibility Generic applicability Needed technical enhancements

Creating awareness of the potential

In the railway domain and in the space domain

Supporting the application of ERTMS in new markets Cost effective solutions for localisation, odometry and communication
