Abstract: The superfluid gyroscope based on low temperature physics science is a new kind of potential high accuracy gyroscope. This paper reviews the progress of research in the field of superfluid gyroscopes. First, several important types of superfluid gyroscopes are analyzed through a comparison of their principles of operation and characteristics. Then, the research trend of superfluid gyroscopes is presented. Moreover, the most hopeful type of superfluid gyroscope based on alternating current (AC) Josephson effect in superfluid is analyzed in detail. The sensitivity and advantages in size and work temperature of such a superfluid gyroscope are estimated. Finally, the possibility of improvements in work principle is analyzed, and the needs of manufacture, refrigeration and error control are summarized so as to develop the technology of superfluid gyroscope based on AC Josephson effect.

Key words: superfluid, gyroscope, low temperature, Josephson effect, principle scheme
