What type of technology does Fiber Optic Gyro represent?

Fiber Optic Gyro (FOG) represents navigation technology because it is primarily used for determining orientation or angular movement in various applications, including aviation, marine navigation, and robotics. The technology works on the principle of measuring the phase shift of light traveling through fiber optics, which allows for highly accurate and stable readings of rotational movement. This precision makes FOG an essential component in inertial navigation systems, guiding aircraft and other vehicles effectively without the reliance on external signals.

In aviation, accurate navigation is critical for flight safety and efficiency, highlighting the importance of such technology in maintaining the aircraft's position and attitude. Fiber Optic Gyros are especially valued in environments where GPS signals may be unreliable, contributing to the overall navigation system's robustness by providing continuous, real-time data on movement and orientation.
