【Abstract】 Atom interferometry gyroscopes（AIG） currently represent the highest theoretically achievable precision in gyroscopic technology. In recent years, various system architectures and implementation schemes have been proposed by domestic and international research institutions. An four-pulse atomic fountain type based atom interferometry gyroscope has been designed and implemented, demonstrating superior angular velocity measurement accuracy under identical volumetric constraints. The fundamental principles are analyzed, and a high-precision angular velocity measurement experimental process is designed. System performance is further improved by alternating the Raman laser frequency difference to manipulate the atomic interference paths between forward and reverse operational modes. Finally, the static performance analysis demonstrates a bias stability of 0.029（°）/h（1σ, 100 s @room temperature）, with an angular random walk of 2.06×10^-6 rad/s/Hz^1/2 and bias instability reaching 1.66×10^-8 rad/s.更多还原
