GNSS use cases in the Railway sector

Regional Railway Lines are key infrastructures to maintain and develop the economy of areas far from large cities.

This public service strengthens social links with towns served. The railway industry is conveying 10 times more passengers than aviation. Thus, this service is poised to become a major user of satellite navigation services to modernize the management of infrastructure and rolling stock.
Therefore, the adoption of GNSS as a key element in signaling developments, simply as an operational tool, has begun. It will require a long transition to adapt the current terrestrial technologies to more efficient systems, based on satellite radio navigation.
