Figure 1 is a schematic of the double-ended tuning fork
quartz resonator used for the gyro sensor. The resonator has
the label ”double-ended tuning fork” because both ends of a
couple of tuning fork resonators are linked. The structure of
the resonator is axisymmetric about each axis. The support
was secured to the base through a spacer with adhesive. The
coordinates in the figure represent the crystalline axes of the
quartz crystal.
