METHOD FOR INCREASING THE ACCURACY uniaxial micromechanical gyroscope AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: physics.;SUBSTANCE: method is based on compensation for the effect of linear acceleration on angular velocity measured by a gyroscope through predetermination of the relationship between the measured angular velocity and the effect of linear acceleration on orthogonal axes X, Y, lying in a plane perpendicular the axis of sensitivity of the gyroscope Z, in form of coefficients , [grad*c/m] and their algorithmic compensation using formula . The device has a monoaxial micromechanical angular velocity sensor with an analogue data output and a base on which a biaxial micromechanical accelerometre is mounted such that the axis of sensitivity of the accelerometre lies in a plane perpendicular the axis of sensitivity of the micromechanical angular velocity sensor.;EFFECT: increased measurement accuracy.;2 cl, 2 dwg
