ATON and SART targets
AIS aids to navigation (ATON) - is presented as a diamond
with crossed lines centred at the reported position of the
ATON. The crossed lines are not more than 2 mm in length
and the sides of the diamond shall be not more than 6 mm
in length.
A virtual AIS ATON shall have the letter ‘V’ superimposed on
the symbol.
The basic colour for an “off position” AIS ATON is red. The
basic colour for an “on position” AIS ATON is as used for the
ATON symbols.
AIS ATON may be labelled.
AIS search and rescue transponder (SART) - drawn with a
solid line and with same basic colour as the AIS ATON
symbols.
NOTE: A radar-SART has a receiver which scans for X band
radar signals. When the SART detects a signal, it transmits its
own signal, consisting of a series of twelve pulses, on the
same frequency. These pulses are displayed as a series of
twelve targets originating at the position of the SART and
spaced 0,6 nautical miles apart along the line of bearing
toward the edge of the screen.
