Reeds Introductions: Essential Sensing and Telecommunications for Maritime Applications covers all fundamental and essential theoretical maritime physics principles which underpin modern marine sensors and telecommunications devices as needed by marine users such as: Navy, Coastguard, Merchant Shipping and users of pleasure craft. For safety at sea, it is vital that maritime users have at least a basic understanding of the key concepts upon which many essential modern sea-going sensors and communications devices now operate.

Knowledge regarding electromagnetic waves and electromagnetic devices is an established merchant navy sea service requirement, particularly for the Standards in Training and Certification in Watchkeeping (STCW95) qualification in various Maritime Coastguard Agency exams, but it is also a practical matter for the amateur as well. This vital introductory book is written as simply as possible to educate an increasing number of maritime users who wish to become familiar and competent with the latest technologies as well as a growing number of overseas students for whom English is not their first language.

This volume provides a comprehensive study of maritime sensors and telecommunications principles and provides a firm foundation prior to reading and studying textbooks in the Reeds Marine Engineering series. Students having read this easy-to-read volume will be better prepared for the more in depth study of that series.
