Abstract: In this paper, the 20 years development history of atom interferometer gyroscope is demonstrated. Atom gyroscope is based on the atomic interference theory, its measurement accuracy and sensitivity are very high and it is an important direction of future high-precious gyroscope, it also has wildly application prospect in inertial navigation field. the recent development of research in atom gyroscope, the innovative approach and the achieved breakthrough in atom interferometer gyroscope engineering were introduced.
