Due to ongoing developments (EGNOS, GALILEO), satellite navigation is about to become an interesting innovation for all fields of transport. One of them is the railway domain, which could considerably profit from the implementation of autonomous on-board positioning systems. Especially for local and regional railway lines, there are various possible applications which could enable a cost-effective modernisation and increase of efficiency.
However, train control poses high demands on positioning with respect to availability, reliability and integrity. These requirements can only be fulfilled by means of integrated positioning systems which combine GNSS with other sensors.
