SEA FLOOR TOPOGRAPHY INFORMATION MONITORING SYSTEM BASED ON GPS INFORMATION OF REFERENCE INDEXES OF CHANGED SEA FLOOR TOPOGRAPHY CAPABLE OF PRECISELY MEASURING SEA FLOOR TOPOGRAPHY INFORMATION WITHOUT RESPECT TO A WAVE FORCE

摘要

PURPOSE: A sea floor topography information monitoring system based on GPS information of reference indexes of changed sea floor topography is provided to maximally maintain the initial installation positions of first and second sonars, thereby obtaining precise sea floor topography information.;CONSTITUTION: A location adjusting device prevents errors of sonars. The sonars(230,240) are installed in a vertical gear and check sea floor topography by a sound wave. A transmission unit(250) is installed an underwater exploration ship body. The transmission unit transmits signals of the sonars to an update server(300). A control unit is installed in the underwater exploration ship body. The control unit controls the sonars and the transmission unit.;COPYRIGHT KIPO 2011
