On May 6th, 2025, the EGNSS MATE project consortium, led by Swiss Federal Railways, iABG, and DLR Institute of Transportation Systems, presented the results of their work focused on advancing safe train localisation using GNSS, sensors, and digital maps. The project aimed to improve the accuracy, reliability, and security of on-board train positioning systems, addressing the need for cost-effective and efficient solutions in the European rail network.

Key achievements of this activity were:

• Algorithm Development: Developed open-source, map-supported multi-sensor fusion algorithms to enhance localisation accuracy. These algorithms integrate GNSS, inertial sensors, and velocity measurements, with a focus on robustness in GNSS outages.
• Jamming and Spoofing Tests: Conducted extensive testing on jamming and spoofing scenarios, evaluating their impact on positioning accuracy and availability. The tests demonstrated the need for robust algorithms capable of handling interference in critical environments.
• Measurement Campaign: Collected a large dataset from dedicated measurement campaigns across the Swiss rail network, providing ground truth for algorithm validation.
• Novel Galileo Services: Explored the use of OSNMA for mission start monitoring and HAS for improved accuracy, with promising results in both static and dynamic conditions.

The project also developed a simulation environment to test localisation solutions at scale, and the results have been made available as open-source tools on their respective GitHub webpages, please visit the links in the slides to access them. Future work will focus on standardisation, testing services for GNSS receivers, and advancing localisation algorithms for various rail applications.
