laser interferometer designed to measure angular velocity
fiber-optic gyroscope
gyroscope that uses fiber optics and light interference
reaction wheel
type of flywheel used for three axis attitude control in spacecraft
vibrating structure gyroscope
gyroscope that uses a vibrating structure to determine the rate of rotation. A vibrating structure gyroscope functions much like the halteres of flies

In surveying, a gyrotheodolite (also: surveying gyro) is an instrument composed of a gyrocompass mounted to a theodolite. It is used to determine the orientation of true north. It is the main instrument for orientation in mine surveying and in tunnel engineering, where astronomical star sights are not visible and GPS does not work.
