Underwater Navigation System Based on Doppler Shifts of a Continuous Wave
The paper describes a concept of an underwater navigation system designed to determine the location and speed of its ROVs or divers. Conducted by the Department of Marine Electronic Systems at the Gdansk University of Technology for several years, research has focused on navigation systems which determine positions on the basis of Doppler shifts of echo signals reflected from a moving object. This article presents a different version of such a system. With a source of a sinusoidal acoustic wave placed on a moving object, four hydrophones, transmitting and receiving electronics and a computer, the system determines Doppler deviations of the received signals and calculates the position and speed of the moving object. Simulation studies and experiment results have shown that the system can offer an alternative solution for tracking its underwater objects.
