Table of NAVTEX CRSs on the above map

Each row in the above table represents one transmitter at NAVTEX CRS with their attributes as follows:

  • Broadcast frequency (kHz) - 518 kHz for International NAVTEX and 490 kHz for National NAVTEX,
  • NAVTEX CRS name - name of NAVTEX CRS,
  • NAVTEX CRS identifier - NAVTEX CRS each have an identifier in the form of a single letter of the alphabet from A to Z,
  • Country - country of NAVTEX CRS,
  • Latitude and Longitude - position of NAVTEX CRS,
  • Broadcast range (NM) - broadcast range of NAVTEX CRS,
  • Transmission times (All in UTC) - begining of a ten-minutes transmitting time slot (almost all NAVTEX CRS transmit every 4 hours),
  • Broadcast language - for International NAVTEX on 518 kHz the language used is English. For National NAVTEX on 490 kHz the national language is used.

NAVTEX CRS each have an identifier in the form of a single letter of the alphabet from A to Z.

Some CRS have more than one transmitter because they are:

  • covering more than one area, for example Niton CRS on the Isle of Wight in the English Channel transmits to the French Channel coast area using the identifier (K) and to the English Channel coast area using the identifier (E),
  • transmitting International and National NAVTEX messages, for example Cullercoats CRS transmits International NAVTEX messages to the UK North Sea coastal area on 518 kHz in English using the identifier (G) and National NAVTEX messages to the same area on 490 kHz in English (as it is national language) using the identifier (U).
