Abstract

This paper deals with the introduction of the satellite navigation into the train control system. That topic has been widely investigated in this last years. To meet the stringent requirements imposed by the railway community the use of an external augmentation and integrity monitoring network is highly recommended. The exploitation of the data acquired by the reference stations can be performed by using a differential approach or by using a double difference approach. In this contribution, we have performed a comparison between these two approaches in the railway domain in terms of both complexity and performances. We made use of real data acquired on field to compare the results achievable with the two techniques and we carried out the SWOT analysis for both of them.
