Maritime Communications Reference Guide

Introduction/Purpose

This guide is designed to describe the characteristics, use and recognition of Maritime Communication Systems and their components. It is not intended to be an exhaustive engineering design manual, rather, its utility is based on the fact that it contains scientifically sound information, but with a minimum of complex mathematics and technical data. Where appropriate, internal and external links are used in lieu of duplicating information that is already available to the public through other reputable sources. This provides a means for further research and depth without interfering with the flow of the main document. The goal of this Reference Guide is to provide the reader with a generalized, intuitive understanding of communications devices and operating principles. It is hoped that experienced engineers, scientists and analysts will find it helpful as a quick reference guide, while those new to the field of maritime electronic communications will find it useful as a supplement to more formal training in electrical engineering or maritime communications analysis.
