Acoustic positioning system for compact underwater vehicle

Currently a platform to investigate the underwater environment is required. In this paper, we propose an autonomous underwater vehicle (AUV) with an accurate positioning system. The positioning system is developed to be accurate enough to utilize the superior navigation ability of our AUV feature. The navigation ability is acquired by the variable vector propeller mechanism. The accurate positi...

Underwater Acoustic Noise Model for Shallow Water Communications

This article presents an empirical model for the noise of the acoustic underwater channel in shallow water from the analysis of field data measurements. A probability density function for the noise amplitude distribution is proposed and the associated likelihood functions are derived. As a result, an expression to the probability of symbol error for binary signaling is presented for the channel...

Properties of underwater acoustic communication channels in shallow water.

Underwater acoustic channels are band-limited and reverberant, posing many obstacles to reliable, phase-coherent acoustic communications. While many high frequency communication experiments have been conducted in shallow water, few have carried out systematic studies on the channel properties at a time scale relevant for communications. To aid communication system design, this paper analyzes at...

Design of an underwater glider platform for shallow-water applications

Underwater gliders are type of autonomous underwater vehicle that glide by controlling their buoyancy and attitude using internal actuators. By changing the vehicle’s buoyancy intermittently, vertical motion can be achieved. Characteristic of glider motions include upward and downward in a saw tooth pattern, turning and gliding in a vertical spiral motion glides without using thrusters or prope...
