A vibrating inertial rate sensor has operational elements that define axes that are rotationally offset or "skewed" from a node or anti-node reference axis. The skew may be relative to separate node or anti-node reference axes, or take the form of an element that is "split" about the same node axis. Both the drive signal and the sense signal may be resolved from a common set of sensing elements. The drive elements may also operate on a skewed axis angle to rotationally offset the vibration pattern to affect active torquing of the gyroscope. Skewed drive elements may be combined with skewed or split elements on the same device. The skewed sensing scheme may be applied to vibratory systems having one or more node axes. The skewed drive scheme may be applied to vibratory systems having two or more node axes to affect active torquing.
