In this paper,we described the progress of cold atom gyroscope.We launched the atoms along the same trajectory accurately and the opposite direction by controlling the frequency of directed digital system circuit.Using stimulated Raman beams,we operated the cold atoms and realized the atom interferometer fringes.With this configuration,it will greatly eliminate the common mode noise caused by uncertainty factor,such as the phase of the Raman laser beams,the gravity acceleration.It will significantly improve the precision in our experiment.The atom gyroscope will give a new way for the inertial navigation technology in the future.

As the core sensors of inertial navigation, the accuracy of gyroscope and accelerometer directly determines the performance of inertial navigation system. With the appearance of cold atom interference technology, it has a wide application prospect in the field of inertial measurement, and cold atom gravimeter and cold atom gyroscope have appeared in succession. This paper mainly introduces the basic principle of cold atom interference technology, and briefly describes the development status of cold atom gyroscope and accelerometer. The existing problems in the current research is summarized, and its future application in navigation are prospected.
