AIS Tracking

The world's largest land based AIS network receiving 61 million position reports per day and 72,000 vessels. Mid-ocean satellite AIS coverage.

LLI has the largest global network of land based AIS receivers reporting on over 6,900 ports and terminals in 132 countries. Each day we receive 61 million position reports from the fleet of 72,000 active vessels. Additional coverage of mid-ocean and poorly populated areas is provided by satellite AIS reports.

All AIS information is displayed in context with the vessel movement data obtained via agent reports, and linked directly with the vessel and ownership details in our database.

For all vessels reporting through our AIS network, the last position is provided as, location name, date time, declared destination, Latitude and Longitude, speed and course over ground.

AIS data for individual or multiple vessels is also accessible through the chart based interface.

The information shown can be filtered by attributes such as vessel, type, flag size. Screen controls enable you to view a particular sea area or to zoom down to the level of individual berths within a port. At high magnification the icons representing vessels are scaled according to vessel size to easy visual identification of trading vessels, tugs and other traffic.

Clicking on the chart vessel position provides direct access to the detailed vessel characteristics and ownership data for that vessel. Display options also enable historical vessel tracks to be viewed.

Historical AIS information is also collected within the system. Real-time AIS data is processed and stored to record the date and time, the distance to the nearest port and whether the vessel is stationary, approaching or moving away from the port. This historical record is extremely useful to identify vessel routing while a vessel is in transit. The processed AIS sightings also provide details of a vessel’s proximity to ports which it passes but does not enter.
