1. An inertial measurement unit (IMU) for measuring an input rate of rotation about an input axis, the IMU comprising:

  • a first three dimensional gyroscope, the first gyroscope configured to sense rotation about a first set of three mutually orthogonal axes, wherein the first gyroscope is disposed such that a first axis of the first set of three axes is oriented at a skew angle in degrees away from a reference plane, the reference plane normal to the input axis;

    one or more processing devices coupled to the first gyroscope; and

    one or more data storage devices coupled to the one or more processing devices, the one or more data storage devices including instructions which, when executed by the one or more processing devices, cause the one or more processing devices to calculate the input rate of rotation based on dividing a sensed rate of rotation about the first axis by the sine of the skew angle.
