Fiber optic gyroscopes (FOGs) utilise the Sagnac effect to measure rotation, forming the core technology behind many modern inertial navigation and rotation-sensing applications. These sensors offer a ...

The persistent narrative of cars that drive or planes that fly themselves will only come true if the on board systems can precisely determine where the vehicle is located at any time. In the aerospace ...

Some days really are longer than others. And now scientists know by precisely how much. Using a laser gyroscope, scientists have measured variations in Earth’s rotation rate smaller than a millionth ...
