FIELD: physics; measuring.
SUBSTANCE: invention concerns to micromechanics field, in particular to micromechanical gyroscopes (MMG) of vibrating type. Determine dependence between quantities of a target signal in MMG and quantity of a voltage between the mobile mass and electrodes of the channel of secondary oscillations using settlement or observational methods at which quantity of the subzero rigidity remains invariable and will converse a target signal of a micromechanical gyroscope to driving voltage Uy between the mobile mass and at least one of electrodes of the channel of secondary oscillations according to certain dependence in which quality it is possible to use quadratic dependence in case of the MMG the unlocked type or dependence of 
(k-constant coefficient) in case of MMG compensatory type. In the MMG for this purpose between an output of the transformer capacity-pressure in the channel of secondary oscillations and an inlet of guidance of a radiant of the voltage joined at least with one of electrodes of the channel of secondary oscillations the block of non-linear transformation of a voltage is entered. Accuracy increase is reached by use of neutralisation of change of a resonant hanger frequency for the account of evaluation of perturbation operating on resonant suspension at change of measured angular velocity and formation of a voltage on electrodes, cancelling this perturbation.
EFFECT: accuracy pinch.
