1. A vibratory rotational rate sensor comprising:

  • a vibratory element including a pair of vibratory masses disposed symmetrically along a common axis for vibration along the axis;

    a driver coupled to only one of the vibratory masses for inducing periodic counter-phase motion in the pair of vibratory masses along the axis;

    a first sense circuit coupled to only one of the vibratory masses for sensing motion of the vibratory mass in only one direction orthogonal to the vibratory axis; and

    a second sense circuit coupled to the same one of the vibratory masses for sensing motion of the vibratory mass in only another direction orthogonal to the vibratory axis.
