Accuracy and reliabilty of systems for the exact identification of facilities along railway tracks. Furthermore the systems are evaluated concerning their suitability for tunnel measurement.

Therefore measurement points are attached at particular positions alongside of the railway track which are exactly determined by means of GPS-RTK recording. These measuring points are the basis for the determination of the measurement accuracy.
