Marine vessel traffic system

A harbor vessel traffic service system, comprising:

• a computer network;
• a plurality of radar sensor means for tracking ship location;
• a plurality of remote site means, connected to said computer network and said plurality of radar sensor means, for obtaining remote site radar sensor data inputs from said plurality of radar sensor means, pre-processing said remote site radar sensor data inputs and inputting pre-processed remote site radar sensor data inputs to said computer network;
• a display;
• and
• a vessel traffic control subsystem means, connected to said computer network and to said display and having a digital database and a processor, the digital database having a digital map of a harbor including all underwater obstacles that pose a danger to shipping, and vessel identification data of potential and current vessels using the harbor, and the processor computing multiple tracks of vessels in the harbor from the pre-processed remote site radar sensor data inputs and digitally fusing and displaying multiple tracks of vessels in the harbor with the digital map of the harbor and displaying a menu of the vessel identification data of an operator-selected vessel onto the display.
