Abstract
Ship communication systems are defined in one part as GMDSS, while the other part consists of systems with secondary importance in safety communications. Each of these devices and systems makes an independent or separate system that works in a specific frequency range and is, at some level, connected to other communication systems. A step forward regarding frequency range and level of networking can be achieved with the application of a software-defined radio. This paper examines a variety of GMDSS communication equipment in terms of technical discrepancy and frequency range. Furthermore, the software-defined radio and SDR configuration development are described according to their theoretical feasibility in the maritime domain. The paper proposes the concept of SDR-based communication systems quite different from conventional maritime communication systems. This approach, conducted in phases, would in turn ease the upgrading, enable flexibility and inter-operation, prolong system life cycle and integrate different maritime communication systems and devices. The proposed concept aims to develop a centralized communication system to incorporate the ship’s communication devices into one common ship communication system.
Highlights
Communication devices and systems on a ship are organized according to the GlobalMaritime Distress and Safety System (GMDSS), which includes various communication devices for a common purpose
Let us look at GlobalMaritime Distress and Safety System (GMDSS) and other communication devices on the vessel through a prism of a software-defined radio
If the problem of software support for software-defined radio (SDR) is not approached in such a way, we have only designed another communication device with improved performance suited for its creator
Summary
Communication devices and systems on a ship are organized according to the Global. Maritime Distress and Safety System (GMDSS), which includes various communication devices for a common purpose. Each of these devices and systems has a dedicated infrastructure, meaning each system has its antenna, control module, peripheral devices, user modules and alike. All devices or systems are networked or interconnected, making the GMDSS system defined on the level of protocols, safety procedures, and communication technology used. To understand what advantages SDR can bring, it is necessary to preview existing communication devices and systems on ships. Let us look at GMDSS and other communication devices on the vessel through a prism of a software-defined radio.
