Presentation

With the digitalisation of transport services, train localisation in real time has become increasingly important for the European railway sector. At present, determination of the position of the train for signalling purposes is based on trackside equipment such as track circuits or axle counters, which are physical elements mounted at specific intervals along the railway track.

The signalling systems on-board the train also use the train odometry to control the speed and carry out the movement authority of the train by estimating the braking curve to protect dangerous points on the network (e.g. closed block, curves, speed limit, etc..).

GNSS could prove a game changer for the European railway network by enabling a significant reduction of trackside equipment and by improving localisation performance. However, fusion with other sensors will be necessary to mitigate the known impact of local effects on GNSS performance.

Capitalising on the achievements of EC and GSA funded projects, key European railway companies have decided to team together and collaborate through the CLUG project for the proof of concept of a “Certifiable Localisation Unit in the railway environment”.

The CLUG project will perform a mission analysis/needs identification and a preliminary feasibility study of an on-board localisation unit with the following characteristics: 

  • Failsafe on-board multi-sensor localisation unit consisting of a navigation core (IMU, tachometer, etc.) brought in reference using GNSS, track map and a minimal number of reference points;
  • On-board continuous localisation system that provides location, speed and other dynamics of the train;
  • Operational and interoperable across the entire European rail network;
  • Compatible with the current ERTMS TSI or with its future evolutions.

Main objectives of the project

Visuel
Mission requirements and definition.

A “top down” approach establishes needs, objectives, and top-level functional and performance requirements of the train localization unit

Visuel
Architecture definition and algorithm prototype development

Identification system concepts that meet the requirements that have previously been defined + analysis of the current and future EGNSS

Visuel
Development of process and tools for certification of localisation unit

Initial development of tools and processes for the qualification and certification of a train localisation unit 

Visuel
Demonstration of the feasibility of a multi-sensor approach

Test prototyped architecture and algorithms in various modes to determine whether requirements are supported using real world data
