The French national rail company SNCF is taking a lead in adopting Galileo technology to boost customer services, in particular in its high-speed TGV network. With almost 50% of TGV trains already equipped with Galileo receivers, European GNSS is enabling improved customer information and traffic management. GNSS is a crucial technology for the digitalisation of infrastructure and autonomous train developments thanks to accurate and safe localisation of trains. Solutions are currently developed through partnerships between space and railway sectors.
