Technology Demonstrator for the certification of a satellite-based ERTMS L2 Regional Line Solution (ERSAT Program)

Customer: ESA – Demonstration Project
Duration: June 2018 – May 2022

The application consists of putting into operation an ERTMS system by using satellite navigation with proper localization device systems and IP-based public telecom (including SATCOM) services instead of the GSM-R. These functionalities are enabled by “services” that are external to the ERTMS, reducing the need to build dedicated infrastructures.
