Abstract
Technologies are provided to recover motion, position, or navigation data of underwater sensors using bathymetry data. A method includes iteratively fitting data obtained by an underwater sensor from interactions between acoustic signals and an underwater floor, and deriving at least one of motion, position, or navigation data of the underwater sensor from the fitting. A standalone sonar can use the methods, systems, apparatuses, and computer programs to realize the derivation of motion, position, or navigation data without a position or motion sensor.
