Temperature Drift of a Hemispherical Resonator Gyro (HRG)

Resumo

The influence of the temperature change of an elastic axisymmetric resonator (hemispherical resonator gyro [1]) on the drift in the inertial space with excited standing wave is studied. Previously, the presence of such a drift was associated with a variety of manufacturing defects in the resonator or the errors of control algorithms [2–5].
