The automatic identification system (AIS) is an automatic tracking system that uses transponders on ships and is used by vessel traffic services (VTS).

Autopilot is the use of an automatic system to control the rudder on the vessel.

Bridge Navigational Watch & Alarm System – BNWAS is a monitoring and Alarm system which notifies other navigational officers or master of the ship if the officer on watch (OOW) does not respond or he/she is incapable of performing the watch duties efficiently.

Echo sounding is a type of sonar used to determine the depth of water by transmitting sound waves into water. The time interval between emission and return of a pulse is recorded, which is used to determine the depth of water along with the speed of sound in water at the time.

A Gyro compass is a type of non-magnetic compass which is based on a fast-spinning disc and the rotation of the Earth to find geographical direction automatically.

Emergency Position Indicating Radio Beacon (EPIRB) is a device to alert search and rescue services (SAR) in case of an emergency out at sea.


The Long Range Tracking and Identification (LRIT) is an international tracking and identification system incorporated by the IMO under its SOLAS convention to ensure a thorough tracking system for ships across the world.



The Ship Security Alert System (SSAS) is a safety measure for strengthening ship’s security and subduing acts of piracy and/or terrorism against shipping.

Marine radars are X band or S band radars on ships, used to detect other ships and land obstacles, to provide bearing and distance for collision avoidance and navigation at sea.
