【摘要】 本文对真实环境中飞行体所感受到的随机扰动进行了仿真。将其转化为随机的线速度和角速度,叠加在理想飞行环境下惯性器件测量得到的比力和角速率上。运用圆锥补偿和划船补偿算法进行动基座情况下惯性导航系统的解算。通过与常规的无补偿的导航算法进行比较,说明本文的算法极大地提高了系统的精度。更多还原

【Abstract】 Random turbulence acting on vehicle in practical dynamic environment is simulated in this paper.The turbulence is transformed to random linear velocity and angular velocity,and superimposed on the specific force and angular velocity measured by the on board inertial instruments in the ideal flight environment.The algorithm of coning compensation and sculling compensation is used in the navigation calculation for the vehicle in the dynamic environment.The navigation accuracy using this algorithm is much better than that of the conventional algorithm without compensation.更多还原
