Development of autonomous acoustic positioning buoy

-Toward low-cost AUV operation-

Abstract

Measuring the accurate position of AUV(Autonomous Underwater Vehicle) is essential for seafloor survey by AUV. In order to deploy positioning system easier, we developed the buoy named BUTTORI, which is capable of autonomous position keeping and measuring the position of AUV by GPS and USBL(Ultra Short Base-Line). In this article, we describe the evaluation result of position keeping and positioning performance of BUTTORI.
