Outline of Final Research Achievements

The purpose of this research is to establish a multiple autonomous-underwater-glider system for realizing a long-term and wide-range monitoring of ocean environments and ecosystems. For this purpose, a solar-powered autonomous surface vehicle (SASV) was developed for the use of assistance in operation of multiple underwater gliders and ocean environment monitoring. This SASV consists of a couple of solar panels with a charge-and-discharge controller, an embedded PC, a couple of thrustors, a GPS device and a 3-axis digital compass for navigation. The SASV has autonomous control mode and manual control mode by small game-controller. Feature of this small-sized, lightweight and low-cost SASV is easy operation. We have also developed kinds of underwater passive acoustic monitoring system (UPAMS) for establishing a soundness index of the ocean, and contributing to preventative safety measures for collision avoidance of high-speed vessels and cetaceans.
