NAVTEX Messages
The structure of a NAVTEX message is to be explained on the basis of following example:
ZCZC PA09
NETHERLANDS COASTGUARD
NAVIGATIONAL WARNING NR. 9 172128 UTC AUG
PLATFORM L10-G 53-29.4N 004-11.7E
UNLIT
NNNN
Each NAVTEX-message begins with the letters ZCZC, followed by the message
identification (PA09). The first letter of the message identification serves the master station
for identification. In this example it is NETHERLANDS COASTGUARD (P).
In the second letter the kind of message is coded, here navigational warning (navigation
warnings). The last two numbers of the message identification (09) are a serial numbers.
The number 00 has a privileged position. It is reserved for distress messages.
NAVTEX messages have a time stamp. It is shown at the end of the third line (172128
UTC August) and means: 17. August, 21:28 UTC. The time stamp refers to the date, the
message was produced and not to the time of the radiant transmission. Afterwards the
message content follows. The message ends with NNNN.
To display NAVTEX messages please follow the menus entries
