NAV6 Series NAVTEX System User Guide Introduction What Is NAVTEX? NAVTEX is a worldwide system for the broadcast and automatic reception of maritime safety information (MSI) in English by means of narrow-band direct-printing telegraphy. NAVTEX provides shipping with navigational and meteorological warnings and urgent information. NAVTEX is a component of the IMO/IHO worldwide Navigational Warning Service (WWNWS) as defined by IMO Assembly resolution A.706(17).

The NAV6 offers simultaneous reception on both the 518kHz international channel and the 490kHz local information channel. Unlike other NAVTEX receivers that discard unselected messages, the large flash memory in the NAV6 means it has the capacity to store all of the messages from transmitting stations within its range.
