GLOBAL SEA COMMUNICATION SYSTEM AT DISASTER (GMDSS)

GMDSS it is based that the search and rescue organizations as well as vessels in area of a place of disaster, should be informed in probably short term on failure and accordingly take part in the coordinated search and rescue operation with the minimal expenses of time. GMDSS should provide also communication with positions of safety and promptness, and also transfer of the information providing safety of navigation, including navigating and meteorological preventions. In other words, any vessel irrespective of area of navigation should be capable to provide communication, reliable from the point of view of safety of the vessel and other courts which are being given area.

Considering, that the various radiosystems entering in GMDSS, have the restrictions connected with an operative range and a kind of given services, requirements to structure of ship radio equipment in GMDSS are certain as follows:

Area A1 - within the limits of an operative range of coastal VHFs of radio stations (20 - 30 sea miles);
Area A2 - within the limits of an operative range coastal MF radio stations (except for area A1) (within the limits of the order of 100 sea miles);
Area A3 - within the limits of an operative range of a geostationary artificial satellite of sea system a satellite communication (except for areas A1 and A2);
Area A4 - the remained zone which is being outside areas A1, A2 and A3.
