Sogei participates in the EU funded Horizon2020 project  ERSAT-EAV, whose goal is to create the first satellite-based positioning system for on-board railway signalling.

This innovative system enables the on-line tracking of trains through control centres at the points of origin and destination, which will increase safety during travel as well as the operating efficiency of the lines currently in service. This, in turn, will allow the rail sector to provide increased service for the transport of passengers and goods.

To reach this goal, a research platform made up of 12 partners from 5 countries and experts and specialists from technology centres, universities, and companies from the rail and aerospace sectors will be designing the system with a budget of 5.5 million euros.

In the ERSAT_EAV project,  Sogei is leader of Work Package 7 'Local Enhancement' for the development and deployment of the Local Augmentation System (Track Area Augmentation System) within the test pilot in Sardinia.

Five GNSS reference stations have been installed by Sogei in  local sites (Cagliari, Vallermosa, Villasor, Guspini, Sanluri)  to provide multi-constellation augmentation data for Rail Traffic Control, ensuring the required level of integrity for satellites, constellations ( including Galileo) and reference stations integrity to TALS (Track Area Location System) for the final broadcasting  to trains to ensure utmost safety criteria and improve traffic efficiency.

At the same time, Sogei is hosting and operating within its premises in Rome, the TAAN Control Centre thus guaranteeing the highest level of security'.

The system will be a significant step forward for operators of local and regional rail lines within Europe, as they represent about 50% of the train journeys currently taking place within the European Community.
