WIB3S Digital receiver for weather and NAVTEX


Navtex (Navigational Telex) is an international automated medium frequency direct-printing service for delivery of navigational and meteorological warnings and forecasts, as well as urgent maritime safety information (MSI) to ships.
Navtex was developed to provide a low-cost, simple, and automated means of receiving this information aboard ships at sea within approximately 370 km (200 nautical miles) off shore.
There are no user fees associated with receiving navtex broadcasts, as the transmissions are typically transmitted from the National Weather Authority (Italy) or Navy or Coast Guard (as in the US) or national navigation authority (Canada).
Where the messages contain weather forecasts, an abbreviated format very similar to the shipping forecast is used.
Navtex is a component of the International Maritime Organization/International Hydrographic Organization Worldwide Navigation Warning Service (WWNWS). Navtex is also a major element of the Global Maritime Distress Safety System (GMDSS). SOLAS Convention mandated certain classes of vessels must carry navtex, beginning August 1, 1993.

NAVTEX Messages:
The equipment is able to receive world-wide the NAVTEX messages of the costal radio stations on the frequencies 490 kHz and 518 kHz. The messages on 518 kHz are sent in English language and on 490kHz they are sent in the respective national language.
The range of the NAVTEX- transmitters varies in dependence of the transmitting power.
NAVTEX messages include e.g.: Nautical warnings, Distress messages, Weather forecasts, storm warnings
Synop Messages
In addition to the well-known weather messages the DWD sends encoded meteorological data of firm weather stations and ships.
The PC Software for the WIB3S decodes these data and indicates it in a map as wind arrows.
Additionally the Synop-data can also be indicated in plain text on PC:
With the help of the internal precision-air-pressure-sensor the air pressure will be stored during a period of max. two days PC seven days).
The air pressure process can be indicated on the PC in form of a gradient
