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

8/6/2019 AIS Presentation1

4/18

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.
