Submarine topography exploration unmanned surface vessel including multi-beam echo sounder

摘要

The present invention relates to a watercraft system for shallow sea submarine topography, and more particularly, to an unmanned marine vessel and a submarine topography exploration area to be explored by an unmanned marine vessel consisting of a catamaran hull and a propulsion unit fixedly installed on the catamaran hull. It includes a driving unit that controls to move and a submarine topography probe installed on one side of the watercraft, and the subsea topography exploration unit includes a multi-beam acoustic echo leveler that measures the depth of water using the speed of sound waves underwater and the multi-beam acoustic echo leveler It characterized in that it comprises an automatic lifting unit for lifting the multi-beam acoustic echo sounder to prevent collision with an obstacle.
