Radio channel in remote control of unmanned underwater vehicles

An ultrashort wave (VHF) radio channel is an effective and flexible tool for organizing real-time communications over relatively long distances on the ground, underground, in the air (space) and on water. This article discusses the classical scheme for controlling the operation of a remotely operated unmanned underwater vehicle (ROV) using a cable, presents an option for using a VHF radio channel as part of a combined communication channel to ensure the operation of ROV when solving a set of operational tasks in the interests of various organizations and departments, and also reflects the prospects development of telecontrol via a combined communication channel for group use of ROVs. The results of full-scale tests on estimating the range of providing communication using such a channel are given, reflecting the possibility of implementing half-duplex communication at a distance of at least 12000 m when transmitting a signal over the water surface.
