Abstract:	One target of the EGNSS MATE project is to analyze the influence of interferences such as jamming and spoofing on GNSS receivers and its impact on the safe localization of trains. As a basis, we use a data set collected over one year on an SBB measurement wagon traveling through the Swiss rail network using two different Global Navigation Satellite System receivers. A first analysis shows that receiver-based flags of jamming and spoofing events are overly sensitive and thus not useful for jamming and spoofing monitoring. Additionally, a heuristic decision algorithm is introduced using the correlation of the front-end gain and the carrier-to-noise power density. The results of the data analysis will be used to derive a set of testable requirements for future GNSS-based train localization solutions.
