Integration of an Acoustic Modem onto a Wave Glider Unmanned Surface Vehicle

Abstract

This thesis examines the possibility of integrating an acoustic modem onto a Wave Glider with the goal of providing a bidirectional communications gateway for submerged sensors, platforms, and networks. The Wave Glider unmanned surface vehicle continuously harvests energy from the environment and is able to hold station without needing to refuel. A unique two-body architecture and wing system directly converts wave motion into thrust, and solar panels provide electricity for sensor payloads. Data messages are transmitted to shore via satellite, and the continuous surface presence means that data can be delivered in real time as it is collected. The objective of this thesis is to identify the best location for an acoustic modem on the Wave Glider, considering the factors of hydrodynamic drag on the vehicle and acoustic performance of the modem.
