Gyroscope systems

Abstract

A gyroscope system includes at least one vibrating structure gyroscope having a structure, one or more drive transducers configured to drive the structure and one or more pick off transducers configured to detect oscillation of the structure. The vibrating structure gyroscope is configured to operate in a sensing mode or a diagnostic mode. The vibrating structure gyroscope being configured, during the sensing mode, to measure an angular rate of rotation of the vibrating structure gyroscope. The system also includes a controller configured to operate the vibrating structure gyroscope in the diagnostic mode such that the one or more drive transducers drive the structure at a frequency other than a resonant frequency of the structure.
