Satellite vessel detection is the process of observing ships from orbit through imagery of the water, rather than relying solely on what a vessel reports about itself. It is how the self-reported picture is enriched and verified, and how vessels that do not report themselves are still accounted for. This guide explains the workflow, from the reported baseline through observation to a usable, prioritized finding.<\/p>\n\n\n\n

Start from the baseline<\/strong><\/h2>\n\n\n\n

Detection is not a blank-slate search of empty ocean. It begins with the AIS baseline, the self-reported picture of who is where. That baseline defines what is already accounted for, and it is what gives an observation meaning. A hull matters differently depending on whether the baseline explains it. Anchoring on the baseline also focuses effort, directing observation toward the water and the questions that need it.<\/p>\n\n\n\n

Enrichment comes from imagery of the sea surface, which shows what is physically present regardless of what a vessel broadcasts. Imagery is sufficient for the great majority of the work. Particular imaging types answer particular questions:<\/p>\n\n\n\n
