Abstract

A method and related system are provided for locating a current position or a coupling location of a mobile unit, which can send or receive for location determining purposes, using a leaky waveguide, wherein a radio signal is fed from the mobile unit into the waveguide or vice versa, wherein the signal is sent by the mobile unit and received by the two transmitting and receiving (T/R) apparatuses, or one signal is sent by each of the two T/R apparatuses and received by the mobile unit, wherein a receiving time is determined for each received signal, and the current position or the coupling location is determined from two such receiving times. The T/R apparatuses, arranged at opposite ends of the waveguide, are synchronized relative to each other prior to the determination of the current position or coupling location, or prior to the reception of the signal.
