CLUG Demonstration of Readiness for Rail

GNSS and SBAS (EGNOS) is amongst the “game-changing” technologies for future digital and automated rail operations, as acknowledged on the longer-term perspective for the evolution of the European Rail Traffic Management System (ERTMS) and in the adopted report on railway safety and signalling from July 2021 which calls for a joint effort towards the introduction of European GNSS in the ERTMS deployment.
CLUG 2.0 (Certifiable Localization Unit with GNSS in the railway environment), a 24-month project started on February 2023, continues the activity of the CLUG project with the same main objective of demonstrating and complement the existing European Train Control System (ETCS) odometry system through an on-board GNSS+EGNOS-based multi-sensor fusion architecture enabling absolute safe train positioning and navigation whilst also transforming the way train localisation is done today. CLUG was focused on demonstrating the feasibility of the multi-sensor fusion approach and defining a safe functional architecture using GNSS and EGNOS. Both objectives were supported by simulation analysis and by real sensor data collection in different test trains. The collected data were post processed by a preliminary prototyped localisation f
