Abstract
In accordance with the present invention, at least three geosynchronous satellites are employed in combination, at respective known positions above a terrestrial water surface to locate an underwater terminal (vehicle). Each satellite includes a light source, and each has a controller for activating its respective light source to simultaneously transmit a light pulse, to a predetermined cell area on the terrestrial water surface, at a precisely scheduled time, t, for receipt by the underwater terminal. A computer at the terminal then evaluates the respective light pulse arrival times, t, to determine the location of the underwater terminal.
