Applied Physics and Mathematics Annotation << Back Development results of MEMS gyroscopes with mutually spaced eigenfrequencies A.V. Soloviev Alternatives designs (differ by kinematics of working path and fabrication technique) of MEMS gyroscopes with mutually spaced eigenfrequencies for russian enterprises facilities are presented. Differential equations of silicon gimbal motion are derived. Choice set to decrease inaccuracy of manufacturing error are suggested. Such operation principle ensure the accuracy enhancement by frequency separation between useful and quadrature components. This hypothesis was confirmed by preliminary test data of developmental MEMS gyroscopes, developed by TsENKI Division Kuznetsov Applied Mechanics Research Institute and produced in Russian Federation, when precision features (bias and its stability, scale factor and its linearity, angular rate range, and cross coupling between channels) were determined. Also, comparison with analogs was made. The keywords: MEMS, micromechanical gyroscope, quadrature error, frequency separation. Contacts: Е-mail: al.vl.soloviev@gmail.com Pp. 03-19.
