SYSTEM FOR CHECKING CHANGED GEOGRAPHIC INFORMATION OF A SEAWATER ROUTE CAPABLE OF VERTICALLY TRANSMITTING A SONAR SIGNAL OF A SONAR

摘要

PURPOSE: A system for checking changed geographic information of a seawater route is provided to precisely measure undersea topography information without respect to a wave force and find undersea topography information with an error, thereby immediately coping with the error.;CONSTITUTION: An underwater exploration ship body moves under water. A location adjusting device prevents errors of sonars. The sonars(230,240) detect undersea topography. A rotational angle measuring device detects the location changes of the sonars. A location tracking device outputs the current location of an underwater exploration ship.;COPYRIGHT KIPO 2011
