Dynamically monitoring the instantaneous zero rotation rate voltage of interferometric fiber optic gyroscope (ifog)


The drift (°/h) for an interferometric fiber optic gyroscope (ifog) means the variations on the voltage generated versus the zero angular (rotation) rate, whilst ifog is not under influence of any angular rate effect.
