Design of an Acoustic-Homing Autonomous Surface Vessel

We designed, built, and conducted trials on an acoustic-homing autonomous surface vessel. After characterizing the performance of a commercially available kayak hull, we installed power, propulsion, and control systems for autonomous operation. The acoustic tracking payload was built up from basic components. We overcame hardware limitations in the microcontrollers and demonstrated acceptable average accuracy in locating the acoustic target. This project demonstrated the feasibility of the overall goal of using a small surface vessel to follow a submerged acoustic beacon.
