Zusammenfassung:	A method and a system for specifying the position of PRU(position reference unit) is provided to precisely specify position information of the position reference unit under a water level. The position of an antenna is measured, and the position of a signal transceiver is specified by using distance information between the antenna and the signal transceiver and posture information of a buoy(102). The distance between the signal transceiver and a signal receiving member is measured. The specifying step and the measuring step are repeated while the buoy is moved to at least three points. The position of a PRU(104) is trigonometrically measured based on the position information and the distance information. An error of the measured PRU position is eliminated.
