1. A vibrating wheel gyroscope comprising:

  • a support oriented in a first plane;

    a wheel assembly disposed over said support and parallel to said first plane, said wheel assembly being adapted for vibrating rotationally in said first plane about a drive axis and being responsive to a rotational rate about an input axis coplanar to said first plane for providing an output torque about an output axis coplanar to said first plane, said wheel assembly comprising an inner hub, an outer wheel, and a plurality of spoke flexures extending between said inner hub and said outer wheel, wherein said plurality of spoke flexures flex in response to rotational vibration of said wheel assembly in said first plane about said drive axis, and are relatively stiff about said input axis and about said output axis; and

    a post assembly between said support and said wheel assembly for flexibly supporting said wheel assembly from said support, said post assembly comprising a post extending substantially vertically from said support and at least one post flexure coupled between said post and said inner hub so as to suspend said inner hub over said support, wherein said at least one post flexure flexes about said output axis in response to said rotational rate, and is relatively stiff about said input axis.
