NAVTEX Receiver
NAVTEX is a system for the broadcast and automatic reception of maritime safety information
by means of a narrow-band direct-printing telegraphy. NAVTEX provides shipping with navigational
and meteorological warnings and urgent information through automatic printouts from a dedicated receiver.
NAVTEX is a component of the IMO/IHO Worldwide Navigational Warning Service (WWNWS) defined
by IMO Assembly resolution A.706(17). It has also been included as an element of the Global
Maritime Distress and Safety System (GMDSS). Since 1 August 1993, NAVTEX receiving capability
has become part of the mandatory equipment which is required to be carried in certain vessels
under the provisions of the International Convention for the Safety of Life at Sea (SOLAS).
New IMO resolution MSC.148 (77) requires NAVTEX receiver implemented on and after
