Long-Range Identification And Tracking (LRIT)

Truly global satellite system for real-time ship identification and tracking. Ships transmit their position automatically, at least every six hours.

What Is Long-Range Identification and Tracking?

  • LRIT is a global satellite-based system for real-time ship identification and tracking.
  • Ships automatically transmit their position at least every six hours and can be polled on-demand to report their current position.
  • LRIT information is sent to the vessel’s flag administration and managed by the Application Service Provider (ASP) through data centers to fulfill LRIT requirements.

Which vessels need to comply with LRIT?

  • All passenger and cruise ships, plus high-speed passenger craft.
  • Cargo ships–including high-speed craft–of 300GRT and up.
  • Mobile offshore drilling units.
