All large ocean-going vessels and passenger vessels are required by the International Maritime Organization to install an AIS transponder and broadcast information about their location and other particulars. Spire captures and decrypts the vessel transponder signal from its satellite constellation as well as land-based receivers. The data is cleaned, attached to specific vessel identifiers, and combined with other vessel-specific information to create a global database of ocean-going vessels that is updated on 15-minute intervals.
