A satellite Automatic Identification System (AIS) is for tracking a plurality of maritime vessels. The AIS 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 actual signal arrival measurements for the AIS messages, and determine a potential spoofing maritime vessel based upon the reported vessel position data and actual signal arrival measurements and send a potential spoof alert to the ground AIS server. The ground AIS server may be configured to perform time sequenced pairwise differential calculations of the actual signal arrival measurements from at least one of the AIS payloads and for the potential spoofing maritime vessel to estimate a position of the potential spoofing maritime vessel.
