>> Product Description
Hemispherical Resonator Gyro (HRG for short) is a high-precision gyroscope with inertial navigation level performance among Colombian vibratory gyroscopes.
Hemispherical Resonator Gyro is a new type of high-precision, high-reliability and long-life solid-state gyroscope. It uses the radial vibration standing wave precession effect of the hemispherical shell lip to sense the rotation of the base. . It has high measurement accuracy, super stability and reliability, good shock and vibration resistance and temperature performance, and especially has a unique shutdown anti-radiation ability. In particular, the life expectancy is as high as 15 years. It is a key component of satellite or spacecraft inertial measurement unit and attitude stability control. It has unique advantages and broad prospects in space applications.
