ABSTRACT:
A navigation sensor, including a gyroscopic element, which has a spin axis, and which has flexure hinge for resiliently mounting the element on a base, and a torque sensing assembly, which has a first piezoelectric beam that is mounted in coaxial relation to the spin axis, and which has a first beam restraining member that mounts a first edge portion of the first piezoelectric beam, and which has a second beam restraining member that mounts an opposite edge portion of the first piezoelectric beam. The first piezoelectric beam is adapted to generate an electrical signal proportional to the angular velocity of the navigation sensor about an axis perpendicular to the spin axis.
