FOG uses the Sagnac effect to measure the rotational angular velocity of an object, which can be used for inertial navigation
Compared with ordinary IMU, FOG-Based IMU uses FOG instead of MEMS gyroscope, which improves the accuracy
Because dead reckoning errors accumulate over time, Inertial Navigation Systems are often combined with other navigation systems, such as GNSS, wheel speedometers, barometers, etc.
