  • What Is SAR and Why It Matters for Vessel Detection

    Synthetic aperture radar images vessels through cloud and darkness. Learn what SAR is, how it detects ships, and how it fits into maritime domain awareness.

  • What Is RF Detection in Maritime Surveillance

    Radio frequency detection locates vessels by the signals they emit. Learn what RF detection is, how it complements imagery, and where it fits in maritime awareness.

  • What Is IUU Fishing

    IUU fishing is illegal, unreported, and unregulated fishing that drains ocean resources and evades oversight. Learn what it covers and how it is detected.

  • What Are Flags of Convenience and Flag Hopping

    A flag of convenience is a foreign registry a vessel adopts for cost or oversight reasons. Learn what it means, how flag hopping works, and why it signals risk.

  • What Is a Vessel of Interest

    A vessel of interest is a ship flagged for closer examination based on risk indicators. Learn what triggers the designation and how analysts build the case.

  • GNSS Jamming and Spoofing at Sea

    GNSS jamming blinds a vessel’s positioning and spoofing feeds it a false fix. Learn how they differ from AIS spoofing and why imagery gives a position you can trust.

  • What Is the Shadow Fleet (Dark Fleet)

    The shadow fleet is a network of tankers used to move sanctioned cargo outside mainstream oversight. Learn what defines it and how its vessels are identified.

  • What Is AIS Spoofing

    AIS spoofing is the manipulation of a vessel’s broadcast position or identity. Learn how it works, why vessels do it, and how imagery exposes a falsified track.

  • What Is Maritime Domain Awareness

    Maritime domain awareness is the effective understanding of activity at sea. Learn what it covers, how AIS and imagery combine, and why context decides what matters.
