An Experimental Result on Information Exchange using USV Communication Relay System

Abstract

In order to safely operate the Unmanned Surface Vehicle (USV) at sea, it is necessary to communicate with Vessel Traffic System (VTS) for information delivery and also manned ship for collision avoidance. For this reason, the communication relay system was designed to enable navigation information exchange in a dedicated communication network via the Maritime Control Station (MCS). However, communication experiment at sea was not conducted to demonstrate the feasibility of the USV communication relay system. In order to validate, experimental scenario was composed of the USV voice relay system according to navigation stages, and communication experiment was conducted in Mokpo sea area. A result of experiment based on the SINPO (Signal strength, Interference, Noise, Propagation, and Overall rating) code described in Document REC. ITU-R SM. 1135, overall rating was good.
