Technology demonstrator for the certification of a satellite-based ERTMS L2 regional line solution (ERSAT Program)

The SBS RailS Phase 2.1 aims at using satellite technologies on the roadmap agreed by the railways stake-holders in the ERTMS MoU signed on September 2016 in order to reduce the ERTMS ownership costs that in turns means a lesser reliance on dedicated railways infrastructures, such as fixed balises and GSM-R telecom network that today are part of the ERTMS solution. Satellite positioning and multi-bearer satcom services are the innovative breakthroughs to be incorporated on a full-scale ERTMS L2 baseline 3 system agreed between RFI and the Italian Railways Safety Agency (ANSF) in coordination with the European Union Agency for Railways (ERA). The new satellite navigation and telecom service demonstrators are the front-runner of cost effective operational services for the ERTMS platform and able to contribute to the modernization of the local and regional lines. The targeted users are railways infrastructure managers and railways undertakers worldwide which will be selecting the ERTMS standard.
