NAVTEX is best described as which of the following?

• A. Navigational Warning System
• B. A satellite weather service
• C. A search and rescue beacon
• D. A digital nautical chart service

Answer: (A)

NAVTEX is a one-way maritime broadcast system that delivers navigational warnings and meteorological forecasts to ships at sea. It relies on coastal transmitters sending safety-critical messages over MF frequencies, which ships equipped with NAVTEX receivers automatically receive and print or display. This setup is specifically designed to provide timely, standardized safety information to mariners so they can avoid hazards and plan safe routes.

It’s not a satellite weather service, which would involve data transmitted via satellites and often more detailed global weather products. It isn’t a search and rescue beacon, whose purpose is to transmit distress signals to summon help in an emergency. And it isn’t a digital nautical chart service, which would provide electronic charts and navigation data rather than routine safety messages.
