Abstract. The article is devoted to the application of the frequency method of measuring the angular coordinates of underwater vehicles by a positioning system which uses chirp signals. The method is designed to determine the spatial position of an underwater vehicle based on the signals of an installed acoustic beacon and uses measurements of the frequency difference of chirp signals received by two or more spaced antennas with a given spatial position. The experiment demonstrates possibility of the practical application the method for measuring the bearings of a towed or autonomous vehicle. The article presents the results of modeling and field tests of the considered calculating angular coordinate method.

Key words: sonar systems, acoustic beacon, chirp signals, methods for measuring angular coordinates, local positioning systems.
