Zusammenfassung:	PURPOSE: A method for recognizing a location by simultaneous map writing using an orthogonal antenna under water is provided to effectively recognize a 3D location using adjacent obstacle information without an existing infrastructure. CONSTITUTION: A sound wave transmitter is arranged in a center. First and second horizontal receivers are horizontally separated. First and second distances between a landmark and the first and second horizontal receivers are calculated(S308). First and second azimuth are measured by the first and second horizontal receivers(S310). A planar orthogonal coordinate based 2D horizontal location coordinate and a planar map are obtained(S312).
