Architecture of a Hydroacoustic Navigation System with a Cotton Basis for Conversion of the Underwater Apparatus to the Docking Module

Abstract

The object of the study are the principles and methods of hydroacoustic reduction of an autonomous underwater vehicle to a carrier. When solving the problem of constructing a hydroacoustic navigation system (HNS), the main systemic issues are the choice of an acceptable method for locating an object in the reduction zone and estimating the options of the proposed navigation system from the point of view of technical implementation. The feasibility of constructing the equipment of a highfrequency hydroacoustic reduction system in the form of a combined information and navigation antenna system combined in base, in which hydroacoustic navigation systems with a short base can be used, is justified; as navigation it is suggested to use data signals exchanged between the docking module and the autonomous underwater vehicle based on the results of measuring the mutual navigation options. The developed sample of equipment is part of a multifunctional network of hydroacoustic communication and should ensure that in a near zone at distances not exceeding 300 m, an autonomous underwater vehicle is brought into contact with the carrier. For this purpose, mutual determination of the distance and angular position of the docking module of the carrier and the autonomous underwater vehicle relative to each other is carried out. Determination of the distance and angular position of the docking module of the carrier and the autonomous underwater vehicle relative to each other is accompanied by the transfer of data between them along the hydroacoustic communication channel. The proposed sample of high-frequency hydroacoustic reduction system (HHRS) equipment of short-range action is intended for operation as part of a complex of technical means providing underwater docking of an autonomous underwater vehicle with a carrier. The obtained quantitative options of short-based HNS are the initial indicators of the first approximation when selecting the necessary parameters of the navigation signal and developing the structure of the AGSS designed to solve the problem of automatically bringing the autonomous underwater vehicle (AU V ) to the docking module (DM) of the given carrier.
