Vibration energy loss mechanisms in high quality factor resonator of gyroscope for space applications

Abstract

Hemispherical Resonator Gyroscope HRG is a state of the art inertial navigation sensor proposed for the future high valued long duration interplanetary satellite missions HRG is a kind of Coriolis Vibratory Gyroscope CVG Mechanical resonator is a very critical functional part of the HRG The performance of the HRG sensor is decided by the resonating structures Quality factor Q factor which is a measure of damping High Q factor means low energy loss from the resonator Ultra high Q facto... newline newline
