The accuracy simulation has become an indispensable technical approach in modern vehicle guidance system design and finalization process. 在现代飞行器制导系统的研制和定型过程中，精度仿真已经成为一种必不可少的重要技术手段。
The majority of the flight is flown using midcourse guidance, during which the missile makes slight adjustments to its trajectory allowing it to reach the vicinity of the target. 飞行的主要阶段使用的是中段制导，在此阶段制导系统不断微调导弹的飞行轨迹使其到达目标附近。
