摘要:
Provided is a method for recognizing a location to control the location of a moving object, the method including: generating a synchronizing signal for a plurality of ultrasonic satellites; the plurality of the ultrasonic satellites simultaneously transmitting ultrasonic signals respectively comprising different frequencies from each other, the plurality of the ultrasonic satellites fixed on predetermined static positions; a receiver, attached to the moving object, receiving the ultrasonic signal and measuring distances between the receiver of the moving object and each of the plurality of the ultrasonic satellites by classifying the frequencies of the ultrasonic signals; and calculating a current location of the moving object by using the measured distances.
