REEDS SEXTANT SIMPLIFIED

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.

RADAR IMAGING FOR MARITIME OBSERVATION

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.

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...
