The material included in the book covers such the important topics as terrestrial magnetism and ship’s own magnetism, essentials of the compass work, coefficients applied, hard iron deviation, heeling error and directive force, vertical force instrument, horizontal vibrating needle, Kelvin deflector and so many others. The book will also be interesting to those who need to understand the basics of the construction and use of the shipboard magnetic compasses.
The correction and adjustment of the compasses have been covered in detail and there is a separate chapter devoted to this. The volume concludes with the performance standards and several theory questions for better tracking of the learning progress. All of the questions have the answers accumulated within the last chapter.
 This training course was developed by the Indian Maritime University in order to provide students with the reference materials for preparation to the relevant examinations. The book is arranged in twenty sections each of them addressing one topic. Starting with the introductory section, the reader proceeds to the DSC, standing for the digital selective calling, and distress, urgency and safety communications.
The RT and Inmarsat communications are discussed in the next sections, followed with the information on EPIRBs, GMDSS two-way VHF radio telephones and SARTs, together with the Maritime Safety Information., or MSI for short. The general regulations governing the use of the radio equipment including GMDSS have been dealt with in a separate section. The students will also find all they need to know about the traffic charging, antennas and power supply, as well as the GMDSS frequencies.
Note that the AIS, LRIT and SSAS have also been covered in detail. The questions and answers for the oral exam have been included for reference. The publication is recommended for use to all those people preparing for their exams and willing not only to get the high results but also to have a good understanding of the subject.
 The sextant has been traditionally treated as one of the critically important navigational tools. The seamen using it properly could determine the correct position line with no reference to any other tool or system. The accuracy of the instrument is sufficient for the safe marine navigation and has been in wide used by many generations of not only seafarers but also airmen.
Even taking into account the existence of the modern electronic navigation systems featuring the ease of use and high accuracy, the use of sextant is still possible and the good understanding of its construction and working principle will be beneficial for all navigators.
The publication will provide necessary knowledge of the sextant, starting with the theoretical basics and then proceeding to the practical instructions on using it; the readers will also find detailed explanations on proper reading and taking sights, adjusting the instruments, and of course handling and taking care of sextant.
The book was written by the professional and experienced Captain Watts and subsequently thoroughly rewritten and updated by Dag Pike, also a very experienced seaman. In short, this is volume will be enormously useful so do not miss a chance.
 And here is the one of the most popular and informative books on the compass error correction. The content of the publication cover all relevant aspects, starting from the very essentials of the magnetism lying in the foundation of the compass working principle. The book opens with the section giving the general introductory information on the magnetic compass errors and how they work, what can cause the error and how the errors are applied and how can they be found.
Then, the author explains the compass correction tables and deviation tables, moving then to the compass adjustment. As you can see, literally everything has been covered, so the reader will get to know everything he or she needs to be able to cope with the compass error. Needless to say that the first thing here is to understand the construction of the compass and its operation.
The book will definitely be so useful to all people with the interest in the celestial navigation and ship handling in general, but will also be appreciated by all people willing to know a bit more about ship navigation. Several appendices to the main content of the book provide additional information. A real must have one, compact and so handy volume.
 The publication is devoted to the maritime observation – this is a term that has been chosen with the intention to cover both maritime surveillance and the remote sensing of the surface of the sea. It should be noted that the subject scenarios seriously differ when it comes to the application, despite the fact that they share a common essential basis, i.e. the sea surface, uniquely characterizing the radar echoes and their proper processing.
The radars have been used for the maritime observations from the earliest days of their appearance on the vessels. To understand how exactly the microwave signals generated by the radar, interact with the sea surface, one shall possess some knowledge of the physics.
There have been numerous studies, including both theoretical and practical, to get clear idea of the backscattering phenomena and better use of radars through improvements of the associated algorithms, including detection and estimation, as well as the classification of the information received. With the introduction of the SAR, standing for the synthetic aperture radar, and high spatial resolution devices, the images are now readily available and the users can apply them for the maritime observation.
 This is one of the latest publications addressing the newly introduced means of electronic ship navigation. Prepared by the recognized experts in marine navigation, the publication will provide the students with the comprehensive, thorough and informative introduction to the global electronic navigation.
