About the book

This book is translated into English from the fifth edition of the Norwegian book "Elektroniske og Akustiske Navigasjonssystemer."

The work with the first edition of the Norwegian version started in 1994. The book is intended for use by students of navigation and nautical science, either enrolled in a class or studying on their own. It is equally
suitable as a reference for practicing navigators at sea, as well technical personnel in related activity ashore.
The intention with this textbook was to include all navigational instruments that are to be found on modern ships. This include advanced survey-, offshore-, DP- and fishing vessels. The content is prepared to the greatest degree possible to cover the description in IMO model courses, as well as the description given in the revised STCW-95 convention (Manila 2010 amendment) on the operational and management level. Some of the system theory must also be considered to have a level slightly above STCW.

The book is divided into 4 parts:

Part 1 presents basic geodesy and line of positions theory, as well as all relevant radio navigation systems. Most emphasis is laid on satellite navigation systems (GNSS), as well as systems to improve the performance of them. Short-range systems used in survey and DP-operations are described. Great weight is attached to performance and limitations of the systems. This part also describes integration of instruments and problems that this entails.

Part 2 describes radar systems, AIS and electronic chart systems (ECDIS). Here is also included a description of techniques for using the systems in a safe and efficient manner, including ARPA and VTS systems.

Part 3 discusses all relevant compass systems, including variants of magnetic compass, gyro and LASER compass, as well as descriptions of the systems which these components are connected to. Therefore, inertial navigation, autopilot and VDR are also included in this part. A relatively large space is dedicated to the description of DP systems. Finally, a short chapter on sextant and bearing devices have been included, since they can be used to verify the accuracy of the different compass types.

Part 4 is dedicated in its entirety to underwater systems. In addition to a description of echosounders, sonars, HPR and speed logs there is introductorily a thorough introduction to underwater acoustics. Several areas of use in fishery and ocean research are described. Further, a thorough review of applications for offshore operations and surveying are undertaken.

Professor Norvald Kjerstad has Master Mariner education from Tromsø University College, and several years’ experience as a navigation officer, surveyor and researcher on different types of ships, including the deep sea fishing fleet, coastguard, tankers, research vessels and icebreakers. He holds a Master Degree and Ph.D. courses from the Norwegian University of Science and Technology (1989). He has subsequently been especially interested in electronic navigation, subsea acoustics and arctic navigation.

Further, during this period he has worked with the development of IMO regulations and with the Norwegian Radionavigation Plan. Kjerstad has issued the textbooks Operation of ships with navigation control, Navigation for maritime studies (in Norwegian) and Ice Navigation, as well as having published numerous international articles and being guesting professor at Singapore Maritime Academy. Since 2004, Kjerstad has been Professor at NTNU (former Aalesund University College), and since 2007 he has been Adjunct Professor at the University of Tromsø and the University of Nordland, Norway.
