NOTE 3 These are the four dimensions from the bow, stern, port beam, and starboard beam
to the horizontal reference point on the ship for which the current "position
reports" are valid. The sum of A + B is the length of the ship in metres, and the
sum of C + D is the width of the ship in metres (See ITU-R M.1371, message 5,
"Reference Point for reported position and Dimensions of Ship."). If the reference

The DTE indicator is an abbreviation for Data Terminal Equipment indicator. Th
purpose of the DTE indicator is to inform distant receiving applications that, if

keyboard and display requirements. The DTE indicator is only used as
information provided to the application layer – indicating that the transmitting
station is available for communications. On the transmitting side, the DTE

The AIS may use the "Talker ID" to identify multiple sources of position data and
