Modern airplanes, drones, guided missiles and spacecrafts require highly accurate and reliable inertial navigation systems. One of the essential components of such systems is the gyroscope, a device that measures the angular velocity of a flying object. Gyroscopes can be realized utilizing various techniques of rotation rate detection – mechanical, microelectromechanical or optical. Nowadays, the optical gyros are widely deployed due to their compact dimensions combined with an excellent performance in terms of excellent stability and low power consumption, which are essential parameters in aviation and space applications ...Continue reading
