摘要： The present invention relates to a method for operating a rotation sensor for detecting a plurality of rates of rotation about orthogonal axes (x,y,z). The rotation sensor comprises a substrate, driving masses, X-Y sensor masses, and Z sensor masses. The driving masses are driven by drive elements to oscillate in the X-direction. The X-Y sensor masses are coupled to the driving masses, and driven to oscillate in the X-Y direction radially to a center. When a rate of rotation of the substrate occurs about the X-axis or the Y-axis, the X-Y sensor masses are jointly deflected about the Y-axis or X-axis. When a rate of rotation of the substrate occurs about the Z-axis, the X-Y sensor masses are rotated about the Z-axis, and the Z sensor masses are deflected substantially in the X-direction.
