1. A multi-axes vibration monolithic gyroscope comprising:

  • a mounting post fixedly attached to a base and defining a first axis;

    a planar mass having a first portion fixedly attached to the post for limited relative rotational movement about two orthogonal axes and a second portion fixedly attached to the first portion for relative vibrational movement and the first and second portions being positioned in a plane perpendicular to the post, the mass defining second and third axes mutually perpendicular to each other and to the first axis;

    driving apparatus mounted adjacent to the second portion of the mass for causing the second portion of the mass to move in a vibrational motion along the second axis; and

    sensing apparatus positioned adjacent to the first portion of the mass for sensing movement of the first portion of the mass about the third axis in response to forces produced by rotational motion and for sensing movement of the first portion of the mass about the first axis in response to forces produced by rotational motion.
