Describe the function scheme of evolutional algorithm error of the simulation model. In which the signal angular motion of the carrier is divided into deterministic motion and random motion. The random motion signal is generated using a shaping filter. To determine the orientation of the carrier, we use the orientation block. In this block, the differential equation is solved using the method of implicit integration. To evaluate the error of determining the attitude of the carrier in the determination block, compare the quaternions obtained with the quaternion defined by initial Euler angles. Ships are taken as carriers with predefined statistical characteristics to conduct the survey. MATLAB software is used to perform simulations to evaluate the effects of vibrational motion. Simulation results show that when the vibration spectrum is wide, the error of orientational determination increases significantly.</span></p> ER -
