Abstract

PURPOSE:To confirm the relative position and distance of moving bodies with each other by furnishing a GPS part to measuring the position of the car of a person concerned, a communication means with other cars, a distance calculation part to calculate their relative distance, and a display part. CONSTITUTION:When the person of a car concerned 2 communicates with other car equipped with a relative position checking device by the use of a car telephone part 4, the factors representing the position information for the car 2 (latitude, longitude, altitude) are modulated by an information transmission part 5 and sent to the mating car via a telephone circuit. At the same time, the signals about position information fed from the information transmission part of the mating car via the telephone circuit are received by a reception part 6 and demodulated. This position information is passed to a distance calculating part 8 and a position display part 9. The always updated position information of the car 2 is received from the satellite 3 by a GPS part 1 for position measuring, and is passed at any appropriate time to a position information memory part 7. When position change is acknowledged, this is stored in memory, and the relevant information is passed to the transmission part 5, calculation part 8, and display part 9. That is, the position information about the two cars is displayed on the display 9 while their relative distance is displayed on a distance display 10, which serves checking the relative position and distance of the two cars concerned.
