Hemispherical Resonator Gyroscope

Spacecraft traversing the solar system carry inertial navigation devices to supplement Earth-based radio navigation. Most use a simple but accurate gyro that measures motion by the change in vibration of a cup-shaped device—similar to how a wine glass “hums” when you rub a wet finger around its rim.
