Abstract
Unlike customary vibrating mass gyros which operate by exciting a first fundamental mode of vibration of the vibrating mass and by detecting the effect of the Coriolis force on a second fundamental mode of vibration of the vibrating mass orthogonal to the first mode, this gyro operates by giving its suspended mass a circular motion alternately in the forward and reverse directions and by deducing the gyrometric effect from the difference between the apparent frequencies of the circular motion of the suspended mass in one direction and in the other. This allows a considerable reduction in the drafting of the heading measurement obtained with this type of gyro.
