One of the key problems that novel high-accuracy superfluid gyroscope is facing is its measure range is very small, so its applying domain is limited greatly. In this paper a method for measure range extension of superfluid gyroscope based on tracing whole pattern is presented, and imlementation scheme of the method is designed. The method utilize the technologies of adjusting area vetor direction and injecting thermal phase shift at initial time to avoid working points of superfluid gyroscope reaching blind points, then the working points can be traced whole pattern. Simulation results show that detecting value of angular velocity can be solved by the method effectively, measure range of superfluid gyroscope is not limited anymore, and rotational polarity can be distinguished.
