SSD – Ship Static Data
This sentence is used to enter static parameters into a shipboard AIS.
The parameters in this sentence support a number of the ITU-R
M.1371 messages.
Ship call sign. A null field indicates that the previously entered call
sign is unchanged. The string of characters "@@@@@@@" are used
to indicate that the call sign is not available.
The characters that can be used in the name are listed in the ITU-R
M.1371, table 14 (6-bit ASCII). Some of the acceptable characters in
this 6-bit ASCII table are reserved characters under IEC 61162-1.
They must be represented using the "^-method" (See IEC 61162-1,
section 5.1.3.). A null field indicates that the previously entered name
is unchanged.
"@@@@@@@@@@@@@@@@@@@@" are used to indicate
that the ship's name is not available.
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 point of "reported
position" is not available, but the dimensions of the ship are available:
A = C = 0 and B > 0 and D > 0. If neither the reference point for the
reported position nor the dimensions of the ship are available: A = B =
C = D = 0 (default). Use of a null field for A, B, C, and/or D indicates
that the previously entered dimension for that parameter is unchanged.
In many cases, the ship's reference point for "reported position" will
be the location of the positioning antenna.
The DTE indicator is an abbreviation for Data Terminal Equipment
indicator. The purpose of the DTE indicator is to inform distant
receiving applications that, if set to "available" the transmitting station
conforms, at least, to the minimum keyboard and display
