Method and system for marine vessel tracking system

DETAILED DESCRIPTION What is claimed is: 1.
A method of identifying marine ships undergoing suspicious activity in predefined zones from a remote location utilizing reports periodically transmitted from the marine ships, comprising: defining zones of suspicious activity and values corresponding to each of said zones of suspicious activity, said values including minimum speed values and change in track values; defining appropriate ship tolerances corresponding to each of said zones of suspicious activity, said appropriate ship tolerances including a time tolerance, a speed tolerance and a change in track tolerance; storing said zones of suspicious activity and said appropriate ship tolerances in a database; via a remote tracking center, receiving ship data including current position data, current speed data and current track data from a ship, the ship having stored ship tolerances stored in the ship and only sending said ship data to said remote tracking center when one of said stored ship tolerances is exceeded; comparing said stored ship tolerances with said appropriate ship tolerances; sending said appropriate ship tolerances to the ship when said stored ship tolerances are not the same as said appropriate ship tolerances; comparing said current position data with said stored geographical zones for determining if said ship is in one of said zones of suspicious activity; selecting the values corresponding to said stored zone of suspicious activity when said ship is in one of said zones of suspicious activity; when said ship is in one of said stored zones of suspicious activity, analyzing said ship data with said values corresponding to said stored zone of suspicious activity for determining if said ship is undergoing suspicious activity; and flagging the ship for investigation when said ship is undergoing suspicious activity.
2.
The method of claim 1, wherein said ship is undergoing suspicious activity if said ship is undergoing maneuvers suggestive of boarding.
3.
The method of claim 2, wherein the ship is undergoing maneuvers suggestive of boarding if the current speed data indicates that the ship is traveling below the minimum speed value corresponding to the zone of suspicious activity
