|Abstract:||GNSS is expected to revolutionize train control systems by providing an efficient alternative to determine the train position along the track. However, GNSS is particularly vulnerable in the rail environment because of the presence of multipath in stations and at many locations along the track. Therefore, particular attention must be placed in assessing and evaluating multipath errors introduced by GNSS when using GNSS to replace physical balises with virtual balises. In this paper we investigate a multipath detector based on the analysis of the double differences of pseudoranges provided by two GNSS receivers on board a train making use of two different antennas. This research, is developed within the RHINOS project co-funded by the GSA that is contributing to the roadmap for introducing GNSS into the European Train Management System (ERTMS).
