[0002] A hemispherical resonator gyroscope is a solid-state wave gyroscope relying on Coriolis effect, representing the advanced development level of inertial navigation sensor technology. It plays a crucial role in the fields of spaceflight, aviation, navigation, and ground strategic / tactical weapon navigation, guidance, and control systems due to its high precision, high reliability, long service life, and low noise. The core component of this device is the hemispherical resonator, made of high-purity fused quartz glass.
