Abstract
A docking system for positioning a vehicle relative to a selective location employs a baseband communication link between the vehicle and the selected location. Transmitters located at specific points at the selective location are activated upon command from the docking vehicle and synchronized 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 at the selected location. These measures are then processed to provide relative positioning information.
