NAVTEX – short for Navigational Telex – is an automated system used to transmit navigational alerts, weather warnings and urgent safety and rescue information. Traditional NAVTEX equipment recorded transmissions as a paper hard copy, but modern NAVTEX receivers use an LCD display and also offer integration with chartplotter and ECDIS systems.
NAVTEX broadcasts are sent on two medium frequency bands – 518kHz (international English language service) and 490kHz (local language service). There is also a long range Marine Safety Information (MSI) service broadcast on HF 4209.5kHz. Transmissions are normally made by the national coastguard and/or weather authorities and is a non-subscription service provided free of charge.
A NAVTEX receiver forms part of the GMDSS mandated equipment package required by law for all commercial vessels over 300 tons. However, because of the vital navigation, safety and weather information that is broadcast over NAVTEX many non-mandate vessels and leisure boats choose to carry a NAVTEX receiver onboard.
A professional grade maritime safety and weather information receiver designed for use on IMO mandatory fit vessels. It provides up to the minute safety information on an easy to read 6” colour display that is viewable even in bright sunlight. Fitted with a tri-channel receiver, the SMARTFIND GMDSS NAVTEX simultaneously monitors the English language, national language and long range NAVTEX services.
