Abstract : This invention relates generally to signal interface circuit boards and more particularly to an interface board providing timing signals from a timing source to a super minicomputer (Q Bus compatible). In developing acoustic signatures for underwater vehicles, it is necessary to have accurate range and bearing data to the vehicle and have that data time correlated with the acoustic signals. Present equipment used for these purposes include the Atlantic Undersea Test and Evaluation Center (AUTEC) Tracking System for providing three-dimensional positional information and the Acoustic Measurement Array for receiving the acoustic signals that are generated by the underwater vehicle. The tracking system determines the position of the underwater vehicle by the use of a pinger attached to the vehicle and bottom mounted hydrophones.
