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 1 July 2005 to include Dual channel reception, 518 kHz and either 490 or 4209.5 kHz, simultaneously.
