The gimbal stabilization mechanism is applied to provide the stability of an object which is mounted on the gimbal by isolating it from the base angular motion and vibration. In this paper the model of one axis gimbal system with dynamic flying object is introduced. The gimbal torque relationships are obtained using Newton’s second law equation with the assumption that gimbal is rigid body. The system is modelled using SIMULINK MATLAB. In fact, the purpose of this research was to analyse the effects of flight dynamics on performance of one axis gimbal system. The simulation results are discussed and compared to show the validity of the gimbal system proposed at the flight path. Also, the results show that the gimbal system stabilizes the line of sight even when the disturbance torques affect the system performance.
