Automatic Identification Automatic Identification SystemSystem

Automatic Identification System (AIS) Automatic Identification System (AIS) enables automatic identification of ships enables automatic identification of ships from other ships and from shore-based from other ships and from shore-based stationsstations

AIS uses a VHF transponder for AIS uses a VHF transponder for transmission of identification and transmission of identification and navigational information from ship-to-ship navigational information from ship-to-ship and ship-to-shoreand ship-to-shore

AIS-equipped ships are able to identify and AIS-equipped ships are able to identify and track each other independetly of shore-track each other independetly of shore-based stations: it is a global system (UAIS)based stations: it is a global system (UAIS)

AIS-equipped shore-stations will use the AIS-equipped shore-stations will use the system to monitor traffic and poll AIS-system to monitor traffic and poll AIS-equipped shipsequipped ships

Purpose of AIS:Purpose of AIS:

Improve situational awarness on board ships Improve situational awarness on board ships in order to prevent accidents and maritime in order to prevent accidents and maritime disasters by means of:disasters by means of:

– automatic swap of navigational information on automatic swap of navigational information on ship’s movements to predict situationsship’s movements to predict situations
