In the world of maritime intelligence, there’s a common misconception that satellite AIS is the primary data source for vessel tracking. While satellite AIS plays a valuable role, it’s terrestrial AIS that serves as the foundation for the most reliable and actionable insights thanks to the much lower data latency—especially in high-traffic zones.
Lloyd’s List Intelligence has built and maintained a proprietary terrestrial AIS network since 2006, pioneering AIS technology as a method of vessel tracking, making it the leading provider of maritime data. Our direct relationships with AIS hosts ensure real-time monitoring, rapid issue resolution, and uninterrupted data flow. This high-performance network is further strengthened by our exclusive partnership with the Lloyd’s Agent Network, which facilitates additional on-the-ground support from Lloyd’s agents worldwide.
Beyond our proprietary network, LLI collaborates with third-party AIS data providers to enhance coverage in key maritime regions. These partnerships allow us to fill potential gaps, ensuring seamless data continuity and the most comprehensive vessel tracking capabilities available.
Our Data Driven, Tech Enabled solutions leverage this robust AIS network to power advanced machine learning models, delivering critical insights to our customers. One example is our AIS spoofing detection model, which uses terrestrial AIS data to identify fraudulent location transmissions—feeding directly into our Compliance Risks tool for enhanced risk assessment.
Furthermore, our in-house analysts continuously monitor AIS network performance, responding to client inquiries with precision by cross-referencing proprietary, third-party, and satellite data. This holistic approach enables us to deliver unparalleled accuracy and reliability in maritime intelligence.
Terrestrial AIS is not just a supplement to satellite data—it is the backbone of maritime intelligence. With Lloyd’s List Intelligence’s established network, dedicated partnerships, and cutting-edge technology, we ensure our customers have access to the most timely, accurate, and actionable maritime insights available today.
