Page 4: Chapter 1. Overview
NAVTEX is an abbreviation for Navigational Telex and it is a Telex-broadcasting system of the coast stations worldwide. NAVTEX of the coast stations broadcasts not only the defined ID, but also all the information on navigational warnings, weather warnings, SAR and other marine warnings for navigational safety of those vessels equipped with NAVTEX Receiver in the coasts. -
Page 5: Transmission Mode
1.2.3. Transmission Mode According to M.625-3 of ITU-R Recommendations, as NAVTEX broadcasting employs 5 Bit Code as ITA No.2 Code System (that is used for international telegraphic transactions by CCITT Recommendations F.1), only 32 characters are available. As it is impossible to display Text, Figures, Marks, Shift Signals only with 32 codes, the system allocates the conversion signals and the figure conversion to Shift Signals and additionally allocates 26 codes. -
Page 6: Transmitted Message Type
) - Serial numbers from 01 to 99 are given in NAVTEX Message. NAVTEX Coordinating Station gives these serial numbers. As a special figure, “00” is used only for significant texts such as rescue and it is unconditionally displayed on LCD screen. In case NAVTEX receives any message with this kind of special figure, it is designed to always print out whatever message it is. -
