ABSTRACT:
A navigation warning system and method for vessels includes one more earth satellites which electro-optically scan whole bodies of water whose signals are analyzed by a computer either on a satellite or at a ground location. The analyzing computer includes a memory which contains coordinates of hazardous ocean conditions. The computer automatically analyzes images generated by vessels travelling within the scanned area and detects when two vessels are on a collision course. Automatic visual and sound indication including a voice recording reproduction unit alerts vessel operators of impending collision conditions. The system may include automatic control of the vessel in response to signals generated by the computer for either modifying the control signals or supplying the computer with information transmitted thereto from the satellite and generated either by analyzing computer in the satellite or by the ground location which is in communication with the satellite and receives information generated by the electro-optical scanner.
