INTRODUCTION TO MODERN NAVIGATION SYSTEMS

Today, constantly and rapidly emerging technology of relatively cheap inertial sensors is readily available and accessible for the navigation today. The present book written by Esmat Bekir is laying the analytical basics required for the proper understanding and implementation of the navigation equations. The content of the book opens with the demystification of the central theme of frame rotation through the algorithms including the quaternion, Euler angles and rotation vectors.

The publication then introduces the calculation issues and also discusses the relevant physical aspects tied to the implementation of all above stated equations, The author has also provided the explanations of the alignment techniques. The content of this book is also featuring the information about the essential algorithms used for the polar navigation. It also demonstrates to the readers how exactly performance of the inertial system can be enhanced when they are aided by GPS.

This text book will be appropriate for the students at higher levels in various fields of engineering (particularly electrical) and will also be very useful for the practitioners in the subject field. The author has managed to capture the fundamental information including theory of the systems, relevant equations plus modeling/simulation issues..

INMARSAT MARITIME COMMUNICATIONS HANDBOOK

This is the fourth edition of the IMC Handbook, which has been revised to include new Inmarsat systems and operating procedures. The handbook has been prepared with the comilers intention to help Inmarsat users get the understanding of how teh subject system operates and how to get the most from it. The handbook is divided into chapters, which each cover a specific subject.

Chapter 1 introduces Inmarsat together with its satellite network, including a summary of the different systems of Inmarsat satcom. The chapter explains how calls are routed between the MES, i.e. mobile earth station and a subscriber connected to the public telecommunications networks. Since 1 February 1999 the GMDSS has become a mandatory requirement on all cargo ships of 300+ GT and all passenger vessels conducting the international voyages. Chapter 2 explains Inmarsats role within the GMDSS and Chapter 6 describes how the Inmarsat-C system is used for the distribution of MSI. Chapter 8 explains die operation of the Inmarsat EPIRB service. Inmarsat-E.

Chapter 3 describes the commissioning procedures through winch every MES must pass before it is allowed to access the network, whether it is a new installation or a modification. Together with Chapter 3. Chapter 4 explains the accounting, billing plus settlement process for Inmarsat-generated traffic for ship-to-shore/shore-to-ship calls. Chapters 5-10 explain in detail how exactly the different Inmarsat systems operate. They include operating guidelines and guidance on how best to operate an Inmarsat MES...

AN INTRODUCTION TO GMDSS

The content of this introductory publication is intended to be of practical use for a broad range of the readers with the interest in marine radio communications. It will also be excellent for the self-learning and we would recommend to go through the pages of the volume prior to taking the formal GMDSS training courses. Individual limitations are commonly imposed to the radio- and satellite systems forming a part of the GMDSS system, relating to the availability and range.

To make sure that all required functions of communications are readily available at any time, the duplicates of the functions considered vital, for example warning, alerting and communications are included. The vessel in distress should be able to automatically alert the coastal state stations and RCC, standing for the rescue coordination centers. The warnings received by these stations will then be passed to the vessels located in that area. The special systems are taking care of the inter-ship communications.

The requirements applicable to the shipboard radio equipment will mainly depend on the area the vessel is currently sailing in. Four sea areas are defined within the GMDSS system. When distress message is sent to another vessel, or to a RCC, the latter is leading and coordinating the whole rescue operation...
