Tilt-measuring apparatus gives precise indication of elevation angle of scientific instrument or other object that must be aimed precisely. In original intended application, apparatus mounted directly on primary reflector of large radio antenna. Sensors and actuator in elevation-angle encoder include motor, shaft-angle encoder, and pendulous accelerometer mounted on shaft. Designed to give zero output when designated reference axis perpendicular to gravity.
