Description

technical field [0001] The invention relates to a system and method for analyzing the influence characteristics of a disturbance gravitational field on different trajectories by a multi-assignment method. Background technique [0002] The factors that cause the deviation of the missile landing point mainly include the error of the guidance tool and the error of the guidance method. The error of the guidance tool is the deviation of the landing point caused by the imperfect performance of the guidance equipment, such as the inertial platform, accelerometer, gyroscope, and computer, which accounts for about 70% to 80% of the total error. The guidance method error is the landing point deviation caused by the imperfect guidance method. With the improvement of the performance of the guidance equipment, the influence of the guidance method error becomes more and more prominent. Among the factors that cause the error of the guidance method, the disturbance of the gravitational fi...
