Zusammenfassung: | A method for calibrating a micro-electro-mechanical system (MEMS) gyroscopes by determining a plurality of variates including quadrature and inphase values from output data of a first subset of the MEMS gyroscopes, determining offset temperature coefficients of the first subset of the MEMS gyroscopes over temperature variation, computing a linear regression using the quadrature and inphase values and the offset temperature coefficients to determine linear regression variate coefficients for predicting the offset temperature coefficient based on the quadrature and inphase values. The method also including determining a plurality of variates including quadrature and inphase values from output data of a second subset of the MEMS gyroscopes, determining a predicted offset temperature coefficient based on the quadrature and inphase values and the linear regression variate coefficients, and programing the second subset of the MEMS gyroscopes to use the predicted offset temperature coefficient to adjust the output data during operation. |
