Iridium Long-Range Identification & Tracking (LRIT)

Reliable LRIT, everywhere on the planet.
LRIT equipment is now a mandatory requirement for ships on international voyages. All ships of 300 gross tonnage and above, including passenger ships, cargo ships, high-speed craft, mobile offshore drilling units and cargo ships must be compliant with the LRIT regulations set forth by the International Maritime Organization (IMO).
