The European Commission’s Directorate-General for Defence, Industry and Space (DG-DEFIS) has awarded two new H2020 mission evolution studies to assess the feasibility of an EGNSS-based safety service for the rail sector beyond 2022, which would enable to rationalise the rail signalling infrastructure.

The European Commission’s Directorate-General for Defence, Industry and Space (DG-DEFIS) has awarded two new H2020 mission evolution studies, EGNSS-R and IMPRESS:

  • EGNSS-R project is led by Airbus Defence and Space with the support of FDC, SNCF, and ESSP;
  • IMPRESS project is led by Egis Avia with the support of Thales Alenia Space and Noordwijk Navigation B.V.

The main tasks of the studies are the development of an appropriate integrity concept for rail applications and the definition of the associated EGNSS-based rail safety service. As part of the user level integrity concept, the projects shall develop the models and algorithms to cope with the challenging local environment of the rail sector. The European GNSS Agency (GSA) will be in charge of the technical supervision of the projects.

When defining the service, the projects shall produce the service concept and consolidate it through iteration with a Working Group of experts, who will validate the final approach. The analyses will also enable the EC to determine the way forward and next steps regarding the EGNSS-based European rail safety service adoption within the rail signalling infrastructure.

European GNSS in ERTMS

Rail signalling systems are used to safely control railway traffic in order to prevent trains collisions. There are currently more than 20 rail signalling systems in Europe since each country has developed its own railway infrastructure, equipment and operational rules. This has led to increased costs and technical and operational complexity of the train sets. Therefore, the European Rail Industry, supported by the EU Institutions, is working on the European Rail Traffic Management System (ERTMS), with an aim to implement a common signalling system for Europe.

The European Commission (EC) is currently specifying the long-term evolution of the EGNSS programme, including new services based on EGNOS and Galileo. The use of an EGNSS receiver in combination with other sensors could result in the provision of accurate and reliable positioning which would translate into an overall improvement of the rail system.
