Deliverable 3.1 - GATE4RAIL - GNSS Characterization in the Railway Domains

In the frame of GATE4Rail project, Work Package (WP) 3 deals with the definition of a comprehensive methodology and the associated tools able to characterise the GNSS performance into the railways application scenarios defined in WP2 in the framework of a Virtual Balise detection in ETCS/ERTMS context. The present document (deliverable D3.1) is the first report delivered by GATE4Rail WP3. It is specifically dedicated to the definition of a standardised database in order to characterize GNSS in different rail scenarios and the description of Consortium tools included in the GATE4Rail test-bed able to generate local and global hazards and evaluate their impact on GNSS performance
