The M-2 gives a clear indication of identity, proximity and bearing of surrounding
AIS targets. By providing this information in both graphic and text formats the
need for ‘bridge to bridge’ radio voice contact between vessels is much reduced.
AIS targets are unaffected by radar shadow effects and remain visible even
when targets may be lost to the vessel’s radar.
Own vessel static and voyage related information is broadcast automatically
every six minutes. Depending on the speed the vessel is making, dynamic
factors (speed, course, heading and rate of turn) are transmitted at intervals of
between two and twelve seconds or every three minutes when moored.
