    The current research on motion of pendulous gyroscope is mainly limited in minute azimuth anglewhich cant satisfy the requirement of quick omnibearing north seeking.Unlike the traditional methodwe made analysis on motion characteristics of pendulous gyroscope in large azimuth angleestablished the motion model based on the Euler dynamical equationsand simplified it reasonably according to the actual conditions.Qualitative analysis of movement stability was made based on the Liapunov stability theoryand the condition where there is only one stable balance point was gained.Simulations show that when the azimuth angle is largethe movement of pendulous gyroscope around its equilibrium point is not a sine curvewhich is different from the case in minute azimuth angle;and the swing period varies with pendulum deflection and torque of suspending string.These conclusions can provide a theoretical basis for quick omnibearing north seeking with a large azimuth.
