Abstract

The challenges of using satellite navigation systems for high precision railway positioning G. Schanzer, U. Schneider & J. Troelsen Institute of Flight Guidance and Control, Technical University of Braunschweig, Germany. Abstract Knowledge of the train position is essential for the organisation and safeguarding of a transport management system to enable the railway to successfully function as a transport service. The position fixes of the respective trains are basic parameters in any operation control system providing functions for a reliable operation and optimal traffic dispatching. This paper presents an innovative technology for railway applications to determine the position fix in real-time, to be reliable and full of integrity and to achieve an accuracy of within two meters along and across the track utilising Global Positioning Service (GPS). 1 Introduction Nowadays, the position of German trains is determined by a block occupancy check.
