Abstract: According to one aspect, embodiments herein provide a whole angle gyroscope comprising a central point, at least one mass arranged symmetrically about the central point, a plurality of transducers, each configured to perform at least one of driving and sensing motion of the at least one mass, and a processor coupled to the plurality of transducers, the processor configured to operate the plurality of transducers to drive the at least one mass in at least a first vibratory mode and a second vibratory mode, identify a rate dead zone of the whole angle gyroscope, and operate the plurality of transducers to apply a force to the at least one mass to reduce the identified rate dead zone of the whole angle gyroscope.
