Improvement in the Method for Bias Drift Compensation in Micromechanical Gyroscopes

In this paper an improvement in method is proposed for thecompensation of the bias drift in micromechanical gyroscopes by achange in the sign of the measured quantity. A general model ofexternal factors of influence is proposed that must be taken intoaccount when the method is applied. An information-measurement systemis developed and experimental data are taken from two commercialsensors. The derived results are showing considerable improvement inthe long-term bias stability when the proposed improvement in method isapplied.
