Navigating underwater using spiral sound

With the increased use of underwater robotics in both Navy and commercial applications, underwater navigation becomes more and more important. As researchers attempt to make these vehicles smaller and less expensive, simple systems for the navigation of multiple vehicles become important. A research team from Naval Research Laboratory, the University of Washington, and Naval Surface Warfare Center has developed and tested an underwater navigation system that uses a spiral shaped acoustic wave to determine aspect. The single stationary beacon can provide a navigation signal for any number of underwater vehicles.
