Abstract

An array of non-identical oscillators, driven by a common external driving force, is synchronized in phase. An example application is the phase synchronizing of non-identical vibratory gyroscopes to provide enhanced gyroscope sensitivity while minimizing the need for gyroscope proof mass alteration and individual gyroscope electronics.
