Multi-mode Coriolis Vibratory Gyroscopes having High Order Rotationally Symmetric Mechanical Structure and 32 Electrodes

An angular sensor, comprising:

• a Coriolis vibratory gyroscope (CVG) resonator, capable of oscillating along:
• a first pair of normal n-=modes comprising a first normal mode and a second normal mode;
• each of the first and second normal modes having one anti-nodal axis;
• and
• a second pair of normal n=2 modes comprising a third normal mode and a fourth normal mode;
• each of the third and fourth normal modes having two anti-nodal axis;
• at least one of a drive electrode and a sense electrode aligned along the anti-nodal axis of each of the first and second normal modes;
• at least one of a drive electrode and a sense electrode aligned along a first anti-nodal axis of each of the third and fourth normal modes mode;
• and
• a pair of bias tune electrodes aligned with a second anti-nodal axis of each of the third and fourth modes if no drive or sense electrode is aligned with said second anti-nodal axis.
