Hemispherical Resonator Gyro is a sensor to measure rotation — vibration is first applied to the hemispherical resonator, then the amount of rotation perpendicular to the vibration is measured.

Hemishperical Resonator Gyros are highly reliable and demonstrates high performance compared to its small size.

Leading the trend of developing low cost, small size MEMS(Micro Electro Mechanical System) gyroscopes, ADD is actively conducting related researches.
