Abstract
The present invention provides a correction for fiber optic gyro drift rate error due to temperature effects based on either the temperature difference between the gyro housing and the sensor spool, or the rate of change of spool temperature. Although gyro drift rate error due to rates of temperature change are virtually unavoidable, adjustments can be made by sensing gyro temperature and calculating the required correction factor. This type of compensation is suited to high accuracy gyros when thermal disturbances are small, or to low accuracy gyros even when thermal disturbances are relatively large. Implementation of this method of compensation requires the development of appropriate electronic circuits to provide the required temperature correction to gyro output.
