Dual-axis yaw rate sensing unit having a tuning fork gyroscope arrangement
Abstract:
A dual-axis tuning fork gyroscope includes four open-ended tuning forks arranged coplanarly in two opposite pairs, a first pair of open-ended tuning forks being arranged opposite one another along a first axis, a second pair of open-ended tuning forks being arranged opposite one another along a second axis, the first axis and the second axis being perpendicular to one another. The four open-ended tuning forks are mechanically coupled together so that all four tuning forks vibrate in the same manner in terms of frequency and phase.
