Linearity is one of the most important static indexes of hemispherical resonator gyro (HRG). Linearity directly affects the measurement error of the HRG in the full range, thus determining the effective range of the HRG. Through finite element analysis of the linearity of the HRG under force-rebalance mode, we can provide a theoretical basis for compensating the linearity by circuit or software, improving the linearity of the gyro combination and increasing the maximum effective range of the gyro combination.
