TXT – Text transmission
For the transmission of short text messages. Longer text messages
may be transmitted by using multiple sentences.
Text messages may consist of the transmission of multiple messages
all containing identical field formats. The first field specifies the total
number of messages, minimum value = 1. The second field identifies
the order of this message (message number), minimum value = 1. For
efficiency, it is recommended that null fields be used in the additional
sentences, otherwise data is unchanged from the first sentence.
The text identifier is a number, 01 to 99, used to identify different text
messages.
ASCII characters, and code delimiters if needed, up to the maximum
permitted sentence length (i.e. up to 61 characters including any code
delimiters).
All fields are used by the AIS.
VBW – Dual ground/water speed
