<p>The method involves measuring the direction and distance of an onboard unit (15) from a transceiver (24) on the basis of wireless communication (23) between the onboard unit and the transceiver. The radiation direction or radiation position of a measuring beam (6) is controlled based on the measured direction and distance and taking into consideration the relative position and location. The relative position is measured by a stationary or mobile control device and is stored in the onboard unit by wireless communication.</p> |
