Analysis of Vibration Noise on the Fiber-Optic Gyroscope
The random noise of the sensor is the main cause of the error in navigation accuracy. In addition, strong downhole vibration will generate greater random noise of fiber-optic gyroscope and accelerometer during MWD operation. The random noise in vibration features concerning time series mutation, slowness and periodicity in its varying. The results show a wide internal noise band and the changing of the noise over time. Considering all these features, this section explores with the dynamic Allan variance method the dynamic characteristics of the random noise produced by fiber-optic gyroscope and accelerometer in vibration, to offer theoretical guidance for improving the environmental adaptability of sensors in vibration and offer theoretical support for noise modeling.
