Which technology is represented by the acronym FOG?

The acronym FOG stands for Fiber Optic Gyro, a technology that has significant applications in aviation and various navigation systems. Fiber Optic Gyros utilize the principles of light to measure angular velocity, relying on the interference of light beams traveling in opposite directions through a coil of fiber optics. This method allows for high precision and reliability in determining the orientation and movement of an aircraft, making it particularly valuable in inertial navigation systems.

Fiber Optic Gyros are favored in aviation because they offer several advantages, including low maintenance requirements, a broad dynamic range, and resistance to environmental conditions that can affect traditional gyro systems. Their ability to provide accurate and rapid measurements of rotational motion is crucial for ensuring safe and efficient flight operations.
