Satellite-Based Train Positioning to Reduce Trackside Infrastructure Costs

transportTestedTRL 5

Imagine if trains could know exactly where they are using satellites, like a super-accurate GPS for rails. Right now, trains rely on expensive physical markers buried in the tracks to stay on course. This project creates a smart onboard system that blends satellite data with other sensors to replace those costly track markers.

The business problem

What needed solving

Current train localization relies on expensive, high-maintenance trackside hardware like Eurobalises. This limits line capacity and increases the cost of deploying and maintaining rail infrastructure.

The solution

What was built

A multi-sensor fusion architecture (LOC-OB System) that combines GNSS and EGNOS for absolute safe train positioning. It includes a functional architecture and validated algorithms for track selectivity.

Business applications

Who can put this to work

Rail Infrastructure
enterprise
Target: National Rail Network Operator

If you are a network operator dealing with high maintenance costs for trackside equipment — this project developed a LOC-OB system that diminishes reliance on Eurobalises. This allows for a transition to moving block operations, reducing the need for physical track circuits.

Rolling Stock Manufacturing
enterprise
Target: Train Manufacturer

If you are a manufacturer dealing with complex odometry requirements for ERTMS/ETCS — this project developed a multi-sensor fusion architecture. It enables absolute safe positioning on-board, making trains more compatible with digital rail standards.

Transport Logistics
mid-size
Target: Private Freight Rail Operator

If you are a freight operator dealing with limited line capacity and long headways — this project developed a safe localisation system. By improving positioning accuracy, it helps increase line capacity and reduces the time between trains.

Frequently asked

Quick answers

What is the cost or price of implementing this system?

Based on available project data, specific commercial pricing is not provided, but the system aims to reduce expenditure for rail infrastructure rollout by decreasing reliance on trackside equipment.

Is this technology ready for industrial scale?

The project is currently demonstrating the readiness of the multi-sensor fusion algorithms and prototyping functions. A complete prototype demonstration is planned for a follow-up activity within the Europe's Rail Joint Undertaking.

Who owns the IP and how is licensing handled?

Based on available project data, IP and licensing details are not specified, though the project is coordinated by UNIFE with a consortium of 15 partners.

How does this integrate with existing rail standards?

The system is designed to complement the existing European Train Control System (ETCS) odometry and is aligned with ERTMS/ETCS Level 3 requirements.

What is the timeline for full deployment?

The current project period runs from 2023-02-01 to 2025-07-31, with further capitalization of results planned in the ERJU program.

Consortium

Who built it

The consortium is heavily industry-driven, with 12 out of 15 partners being industrial entities (80% ratio). This high concentration of industry players, including major operators like DB, SBB, and SNCF, suggests the project is focused on commercial viability and practical deployment rather than theoretical research.
