Abstract
A two axis rate gyro for sensing angular velocity about two input axes includes a rotating disc which is bearing mounted in a framework. A motor is provided for driving the disc rotationally in the bearing mounts. Pickoffs are mounted in the framework which are spaced from the faces of the rotor and oriented along axes which are orthogonal to the two angular velocity input axes. Circuitry is provided for receiving the outputs from each of the orthogonally oriented pickoffs, including circuit means for removing noise in the outputs due to variation caused therein by spacing variation between the rotor faces and the pickoffs resulting from departure of the rotor faces from a flat condition.
