In a system for information/guidance and mechanised parking of aircraft at a carefully predetermined stopping point in an airport, a display unit which is positioned in front of the stopping point, and in or closely adjacent thereto a microwave antenna which emits waves towards the aircraft, which waves are reflected back to the antenna and received thereby. By measuring the time difference between the emitted and the received waves the aircraft position can be analyzed with great accuracy by a computer and be indicated on the display unit. |
