Abstract
A method and apparatus for controlling dither in a multiple gyro system. Each gyro is driven at a distinct nominal frequency. The resulting gyro motions are measured, then demodulated to determine their cross-axis frequency content. Virtual drive signals are generated in light of the cross-axis interactions, then combined with the nominal drive frequencies in such a way that the measured cross-axis effects, resulting in either signal intermodulation or block coning, are nulled.
