AIS technology relies on global navigationsystems, navigation sensors, and digital
communication equipment (i.e. transponders)
operating according to standardizedcommunication protocols that permit the
voiceless exchange of navigation information
between vessels and shore-side vessel traffic
centers

AIS transponders on vessels can broadcast
information about the vessel, such as itsname or call sign, dimensions, type, position
(derived from a global navigation system),
course, speed, heading, navigation statusand other pertinent navigation data. This
information is continually updated, and
received by all AIS-equipped stations in its
vicinity.
