    First Pass Detection

    A key technical element for measuring the success of a Satellite AIS system is a term called First Pass Detection (FPD). FPD is the ability for a single satellite to maximise the reception of AIS messages, especially in high density shipping areas like Gulf of Mexico, South China Sea, or the North Sea. exactAIS is the only system capable of achieving the levels of FPD necessary for achieving true maritime domain awareness.
