The present support course is based by IMO Model Course (GMDSS GOC) 1.25+ Compendium. Radio has been the foundation of the distress and safety systems used by ships at sea since the first instance of the use of radio to save lives at sea more than a century ago. In order to be effective, a radio-based distress and safety' system has to be founded on internationally agreed rules concerning the radio frequencies used, type of equipment and operational procedures. The first international agreements were established under the auspices of the predecessor to the ITU. Many of the operational procedures for Morse telegraphy established at the rum of the century have been maintained to the present day. This publication covers such an important topics as basic concepts of the GMDSS, basic receivers and transmitters, DSC, radio wave propagation, telex procedures, DSC terrestrial distress communications, INMARSAT satellites, MSI, radiotelephony procedures, and many more. In addition, the book is supplemented with a Glossary ot terms.
