Fiber Optic Gyroscope (FOG) is an inertial sensor that measures rotational motion without mechanical moving parts. It leverages the Sagnac effect observed in a coil of optical fiber to detect angular velocity with high precision and stability. FOG units are widely used in aerospace navigation systems, unmanned platforms, precision surveying equipment, and autonomous control applications where low drift and high reliability are required. This article examines FOG parameters, functionality, common questions and answers, and future trends in the context of navigational and measurement system integration.

Fiber Optic Gyroscopes are integral to systems requiring high‑precision rotational sensing such as:
FOG technology is selected where mechanical gyroscopes lack reliability or where MEMS gyros do not meet precision requirements. The inherent absence of moving parts increases reliability and reduces maintenance.
A Fiber Optic Gyroscope uses the Sagnac effect, where two light waves propagating in opposite directions around a coil of optical fiber experience a phase shift proportional to angular rotation. This phase difference is converted into an electrical signal representing angular velocity.
Compared with MEMS gyros, FOG offers significantly lower drift and better long‑term stability, making it suitable for high‑precision navigation. Against Ring Laser Gyros (RLG), FOG typically has fewer maintenance concerns and does not suffer from lock‑in issues; however, RLG may still compete at the highest performance layers in aerospace applications.
Temperature variation and mechanical vibration are primary environmental factors. Advanced FOG modules incorporate thermal compensation and vibration isolation to maintain angular stability. Proper calibration procedures and environmental shielding further mitigate these influences.
Integration of a Fiber Optic Gyroscope into an inertial navigation system requires synchronization with accelerometers, GPS receivers, and control processors. Calibration data and alignment matrices ensure that the rotational data from the FOG is properly fused with translational motion sensors to produce accurate position and orientation outputs.
FOG technology continues to evolve with improvements in optical fiber quality, photonic components, and signal processing algorithms. Future directions include:
Market demand for reliable navigation systems in autonomous logistics, space exploration, and defense sectors is driving ongoing innovation. Cross‑disciplinary advancements in materials science and integrated photonics are expected to lower production costs while enhancing performance.
