ABSTRACT:
A rudder control circuit for an automatic steering system of the type which includes a known sensor circuit and a reference input circuit selectively connected thereto for easy zero-point calibration separate from the normal control operation is disclosed. The control circuit also includes a high impedance indicator circuit connected to the main feedback line of the control circuit for visual indication of rudder angles with minimized disturbance on the feedback control. The control circuit is further advantageously accompanied by a remote steering unit including a manually adjustable and automatically resettable manual steering circuit for easy steering by single operator.
