PURPOSE:To enable employment of the title system as an operation control system for many moving bodies by providing a map data base and an apparatus such as an image processor collectively in a specified place and thereby making a navigation system simple and highly functional. CONSTITUTION:A signal from a GPS satellite is caught by a GPS antenna 1 and enters a GPS receiver 2. An output of the receiver 2 gives a speed information which is calculated from a position information of a moving body 12 and the state of change thereof. These informations are synthesized with an information of a generator 7 of an identification signal specified for the moving body 12 and they are delivered, through a radio transmitter-receiver 9, from an antenna 11 as a wave. These informations of the moving body 12 are inputted to an image processor 14 through a transmitter-receiver 15 of a fixed station 16. Besides, a map information of a map data base 13 is taken out by the processor 14 and synthesized with the received position information to be an image signal. The image signal of the moving body 12 is received by the antenna 11 and demodulated by the radio transmitter-receiver 9 and the image signal sent from the fixed station 16 is obtained. This image signal is displayed by an image display unit 10. The moving body 12 can recognize its own position from the image. |
