CONCEPT FOR LOCATING A POSITION ON A TRAVEL PATH

摘要

A device for locating a position on a travel path, with which radio signals can be received along the travel path from permanently positioned radio transmitters, having a device for determining properties with the radio signal of the permanently positioned radio transmitters at the position, and a device for comparing the specific properties with previously recorded properties which characterize a reference travel path and for defining a relationship between the position and the reference travel path on the basis of a result of the comparison.
