High sensitivity rate-integrating hemispherical resonator gyroscope with dead area compensation for damping asymmetry

Abstract The rate-integrating gyroscope (RIG) operation is considered as the next generation architecture for hemispherical resonator gyroscopes (HRGs) with advantages of direct angle measurement and unlimited dynamic range. However, this RIG operation requires high symmetry for the HRG device and t...
