STARS project description



GNSS applications in Railways are become more and more frequent. So far the focus has mostly been on non-safety related applications, such as in passenger information systems and for freight logistics, which are also typically not standardised. For these applications the current knowledge of the behaviour of GNSS in the railway environment is largely sufficient, or can be obtained by companies individually.
When moving GNSS application into the domain of safety, such as for train control systems, a much better understanding of GNSS behaviour is needed. This is especially true for the use of GNSS in standardised applications, such as ERTMS, where performance of GNSS receivers has to be harmonised in order to achieve standardised, guaranteed performance and thus interoperability between on-board units of different suppliers.
