E-GNSS enabled railway signalling – from vision to action

The European Union Agency for the Space Programme is working together with rail and space industry stakeholders to enable satellite-based positioning for railway signalling. EGNSS solutions are associated with cost and efficiency benefits, such as reducing infrastructure elements needed for train control systems.

At the heart of this multi-stakeholder initiative lies the European Train Control System (ETCS), currently being adopted in Europe and beyond as one of the components of the European Rail Traffic Management System (ERTMS). At present, within ETCS, train localization relies on “balises,” physical elements mounted at specific intervals along the railway track. The main goal is to ensure that wherever possible, GNSS-based localisation is used instead of the trackside elements without any operational or safety implications on the ETCS. The updated roadmap, reflecting the changes in the R&D landscape and inclusion of new funding instruments, summarises the main projects currently running and planned, as well as the involvement of the various stakeholders interested in achieving the objective of EGNSS enabled ETCS.
