Cross-coupling of the oscillation modes of vibratory gyroscopes
This paper reports for the first time on the results of the advanced gyroscope design of HSG-IMIT with the double decoupling mechanism. In connection with the measurement results, particularly to characterize the effectiveness of the decoupling, the cross-coupling of the driven oscillation and the detection oscillation is investigated, discussed and evaluated in detail by theoretical modeling. A description of the measurement signal and the so-called quadrature signal is deduced and a comparison with the gyroscopes of HSG-IMIT realized according to the single decoupling principle DAVED is accomplished.
