In recent years, the rapid development of atom interference technique provides a new way for rotation precision measurement and the related applications. The sensitivitiy of atom interferometer is higher than that of the traditional optical gyroscopes. It is a new generation of inertial measurement instrument, and it has great application prospects. The basic principle, main performance and technical characteristics of Raman-type atom interferometry gyroscopes are introduced. The latest research progress in the field of Raman interference type cold atom gyroscope is presented. The research status and development prospects are analyzed.
