THE MARINE NAVTEX RECEIVER :

MARINE NAVTEX RECEIVER :-

NAVTEX RECEIVER is a simple , reasonable and cost effective but sophesticated medium of receiving the telex messages. It is particularly used for receiving MSI ( Maritime Safety Information's ) on board a ship .The  Navtex receiver machine is fitted with a Printer on board ships which immediately starts printing the received messages , thence putting no burden on the user for the setting up of printer every time a message is received.

This type of reception facility is called Narrow Band Direct Printing (NBDP) OR    Telex Over Radio ( TOR).

Navtex receiver is fixed  or tuned to receive the telex messages or MSI's on the following frequencies.

  1. 518 KHz ( messages in International English Language )
  2. 490 KHz ( messages in the national language )
  3. 4209.5 KHz ( this frequency might be used in some tropical regions )

These MSI or NAV WARNINGS ( Navigational Warnings ) are transmitted by the transmitting stations and  Navarea Coordinator's of the concerned NAV-AREA.

For the purpose of simplification of station identification and identification of message type and it priority , the whole world is divided in to 18 NAVAREA  /  METAREA. (INDIA- falls under Navarea /Metarea  - VIII )

In one Navarea  there may be 24 stations , segregated in four groups . Each station has a 60 minutes transmission time allotted in one day ,  for transmission of MSI / NAVWARNINGS / METWARNIGS etc.

Receiver of the Navtex messges , by virtue of his instruments capabilities has the ability to select or reject the wanted or unwanted transmission station or message types. Certain type / category of messages can not be rejected by user, such as :

  • NAV WARNINGS
  • MET WARNINGS
  • DISTRESS MESSAGES
