<p>A system for positioning or docking a vehicle relative to a selected location employs a baseband communication link between the vehicle (Z) and the selected location. Transmitters (T,Q,R,S) located at specific points at the selected location are activated upon command from the docking vehicle and synchronised with reference signals radiated therefrom. Time delays between the arrival of each signal radiated by the transmitter and the initiation of a reference signal are determined to establish measures to the different points (T,Q,R,S) at the selected location. These measures are then processed to provide relative positioning information. </p> |
