Abstract : The patent relates to a tracking system whereas movable crosshairs on a television monitor are controlled by a circuit responsive to manual control, and a television camera is controlled by a circuit responsive to the same manual control. The crosshairs are centered on a contrasting target in the field-of-view of the television system in response to the manual control. The system is then switched to an automatic mode of operation, and moves the crosshairs and the camera to keep the crosshairs on the target, and the target centered in the field-of-view. A hardstick providing outputs directly related to the pressure applied thereto is the manual control.
