| Abstract: | In practical uses, gyrowheel or gyrorotor often drifts away from its gyroaxis because of various factors, thus, influencing its azimuth measurements. Analysed are the causes that lead to drifting, methods for drift inspection and what should be cautioned while inspecting; Mainly detailed are two math methods for correcting gyroscope shift, i. e. ,unvariable drifting rate method and azimuth correcting method. By using these methods, real and accurate gyroscope drift values are obtained. |

| Keywords: | gyroscope measurement precision drift correction variable drift rate linear fitting |
