The maritime shipping history has demonstrated that serious changes are sometimes made being a logical consequence of the events. The engineering related changes are normally resulting from the escalating technological developments. These criteria lead to the changes in the methods used for distress alerting and maritime communications globally.
The publication is intended to help readers get better understanding of the GMDSS systems and also will be very useful when applied when preparing for the examinations. It was released to provide new radio operators and electro-technical officers with the due technical knowledge that is needed to properly understand the GMDSS together with all related systems.
The book is made of three sections and the first section gives general information about the GMDSS so can serve as a good introduction to the subject. The second section is dealing with the impact that the sat communications have today and explains the use of the satellite technology, paying particular attention to Inmarsat. The last section of the publication considers the main principles of the terrestrial radiocommunications. All systems and equipment have been explained in detail.
