METHOD FOR DETERMINING PARAMETERS OF WAVE SOLID-STATE GYROSCOPE Russian patent published in 2015 - IPC G01C19/56 

FIELD: measurement equipment.

SUBSTANCE: proposed method can be used at manufacture and preparation for operation of wave solid-state gyroscopes (WSG). Determination of WSG parameters consists in the fact that amplitudes of oscillations of the resonator on frequencies near resonance in stationary modes are measured; as per measured values of amplitudes of oscillations and frequencies there shaped is a vector and a matrix with elements that are linear relative to amplitudes. Amplitudes of oscillations are increased by two-three times; a matrix with elements that are not linear relative to amplitudes is shaped and coefficients of non-linearity of resonator oscillations are calculated simultaneously with parameters of a wave solid-state gyroscope.

EFFECT: proposed method allows improving accuracy of determination of WSG parameters by several times.
