摘要： Provided are a method and a system for recognizing a location to control the location of a moving object by installing an ultrasonic satellite transmitting an ultrasonic signal. The method includes generating a synchronizing signal at a plurality of the ultrasonic satellites. The ultrasonic satellites simultaneously transmit the ultrasonic signals respectively having different frequency from each other. A receiver of the moving object receiving the ultrasonic signal measures a distance between the receiver of the moving object and each ultrasonic satellite by classifying a frequency of the ultrasonic signal, and calculates a current location of the moving object by using the measured distance. The system includes ultrasonic satellites for transmitting ultrasonic signals, a moving object for recognizing a current location by receiving the ultrasonic signals from the ultrasonic satellites, a reference time broadcasting device for providing a synchronizing signal to the ultrasonic satellites and the moving object in operation, and a server for providing coordinates of the ultrasonic satellites to the moving object.
