Be aware of changes in draught of dark vessels to detect unreported goods transfer in time.
Dark vessel draught indicates how "full" a vessel is. Estimating draught of dark vessels, e.g. oil tankers or cargo ships, after every stop shows if the vessel became lighter or heavier. Depending on this change, the conclusion on unreported good or commodity transfer can be derived.
With the constellation of small Synthetic Aperture Radar (SAR) satellites, ICEYE can provide accurate information on estimated draught of dark vessels.
