Abstract
An Automatic Identification System (AIS) for tracking a plurality of maritime vessels may include a ground AIS server and a constellation of Low-Earth Orbit (LEO) satellites in communication with the ground AIS server. Each LEO satellite may include an AIS payload configured to receive AIS messages from the plurality of maritime vessels and determine therefrom reported vessel position data, determine an actual frequency of arrival (FOA) for each of the AIS messages, determine an expected FOA for each of the AIS messages based upon the reported vessel position data for each AIS message, determine a potential spoofing maritime vessel based upon a difference between a corresponding expected FOA and actual FOA for a given AIS message, and send a potential spoof alert to the ground AIS server.
