Abstract

For GALILEO-based train-borne positioning systems, the digital map is a very essential and important element since it enables relating the measured sensor data to the geometry and topology of the track. This contribution points out the relevance of the digital map within a map-matching process, which is necessary for all GALILEO-based train positioning systems. It also focuses on the generation of a digital map and on the functional requirements a map has to fulfill e.g. for safety-critical applications. Finally, an idea is presented how the accuracy and availability of the result of the train-borne positioning system can be significantly improved by extending the map by environmental-specific attributes and using this information for the evaluation of the sensor data in the data fusion process.
