The objective of this activity is to study the suitability of the current generation of SBAS for use in an evolution of the European Rail Traffic Management System (ERTMS) using GNSS for virtual balise detection.

This activity focuses on the current generation of the European SBAS, EGNOS v2 (GPS L1 only) and includes the following aspects:

Review and consolidate requirements and assumptions on virtual balise detection in ERTMS using GNSS;

Suitability analysis of the current EGNOS system design for its use in ERTMS, confirming the feasibility of current system allocations; and

Analysis, by an accredited independent safety assessor, of the suitability of the existing EGNOS Safety Case for cross-acceptance by railway safety authorities.
