PURPOSE: A movement body height calculation method in a location recognition system capable of assuming the location of the movement body is provided to calculate the height of the movement body applied according to a scatter or an obstacle. CONSTITUTION: A method manufacturing a moving body height is as follows. The radio frequency signal is sent in the beacon installed in the movement body. The ultrasonic wave transmitted from the beacon. Distance data between the beacon and the movement body is calculated and stored(S105). The location of the moving body is estimated through the preexistence triangulation calculation. The height of the moving body is produced among the constellation in which it produces by the specific coordinate usage.
