Yotta Navigation and The Ohio State University propose to develop a complete diver text messaging and locator system. The system will securely transmit preformatted and free-text messages, and will be able to accurately determine range and bearing, at distances of up to 1000 meters. This system consists of two major components. An ultrasonic cylindrical array, mounted on a swimmer delivery vehicle or similar platform, serves as a central node. This central node both communicates with and determines the location of individual divers on the system’s acoustic data network. Individual divers carry a small portable device which contains an integrated miniature inertial navigation system, an ultrasonic transducer for communication, as well as a full-color graphical user interface. The system will build on previous research and development work conducted by Yotta Navigation, and will take advantage of the substantial modeling, simulation, and test capabilities developed by Ohio State University. As a result, an initial prototype system can be developed by the conclusion of Phase I.
