  • Page 8: Features

    Search and Rescue (SAR) information and other navigational information for NAVTEX receiver-equipped vessels sailing in coastal waters. The FURUNO NX-300 NAVTEX receiver receives NAVTEX messages and automatically displays them together with station ID and message category information. The service range of a NAVTEX station is typically 200-400 nautical miles. A NAVTEX station normally broadcasts every 4 hours.

  • Page 11: Principle Of Navtex System

    1. PRINCIPLE OF NAVTEX SYSTEM How NAVTEX Works There are many types of navigational and meteorological information available on radio, such as NAVAREA, HYDROPAC, etc. However, these systems rely heavily upon the operator's experience and skill in tuning the radio and interpreting messages. In addition, constant monitoring to pick up wanted information among a vast volume of messages is not practical with a limited radio staff.

  • Page 12: Message Format

    1.3 Message Format For automatic identification of messages, each message starts with eight control characters, called "Header codes". The first four characters are always "ZCZC" and common to all messages. This part is used for message synchronization. The latter four characters are designated as b1, b2, b3 and b4 to indicate origin, category and serial number of the message.
