NAV6plus System V3

Dual Channel NAVTEX Receiver and Display

The ICS NAV6 series of NAVTEX receivers have long been synonymous with the high quality manufacturer and reliability throughout the product range.

The NAV6 was the world's first LCD NAVTEX system to offer dual channel (518kHz and 490kHz) reception as standard. Information is presented on a large and easy-to-read LCD display, rivalling paper print-out for legibility.

NAVTEX is part of the Global Maritime Distress and Safety System (GMDSS). It broadcasts weather and navigation warnings in English on 518kHz every four hours from transmitters around the world. Increasingly, local language and small craft information is also transmitted on 490kHz. Urgent messages such as gale warnings can also be transmitted in between scheduled transmissions when necessary.


NAV6plus System V3 Features

The NAV6plus System V3 is now available for purchase. The new NAV6plus system has all the capabilities of the standard NAV6 with the addition of GPS and NMEA repeater displays and a new digital barograph feature. There are also options to upgrade earlier versions of the NAV6 systems. Please contact ICS or your dealer for advice on the best upgrade options for you. All NAV6 NAVTEX Systems are available without a Antenna option.
