The tide analysis method was used to analyze and assess the accuracy and stability of digital deformation observation in Xinjiang.The results showed there was better consistency between the latitude distributions of main wave tidal factor and theoretical value, and the quadratic mean deviation was very small. The observation accuracy of all observation instruments met or surpassed the standard of class 1 deformation stations of China Earthquake Administration. The observation instruments of ground tilt have higher accuracy and better stability; especially all the indices of water tube inclinometer are higher than other type of instruments. The study indicated there was obvious deviation in the determination of direction and azimuth in several stations.
