b. Automatic Identification System (AIS) 

AIS  is a  ship-reporting system based on messages broadcasted  by vessels carrying 

transponders. It  was developed primarily as a tool for maritime safety  to avoid  vessel 

collision  by Vessel Traffic Services (VTS) and as a means for coastal  states to receive 

information on vessels operating near their coasts. AIS transponders  send and receive 

signals, using a very high-frequency (VHF) transmitter, broadcast to receiver devices on other 

ships or to land-based systems. By sending and receiving regular communications about their 

identity and course, vessels can avoid collisions and navigate safely in low visibility.
