What is LRIT?
The Long Range Identification and Tracking system is a mandatory IMO requirement under the SOLAS convention. It enables the tracking of ships remotely over satellite communication, enhancing global maritime safety, security, and environmental protection. Ships transmit their identity, location, date, and time at regular intervals to a Data Centre via satellite communication systems like Inmarsat or Iridium.
