摘要: 传递对准是提高惯性导航系统初始对准速度与精度的有效方法,而杆臂效应是影响传递对准精度的重要因素之一。本文通过分析杆臂效应的形成原因,建立杆臂效应速度和加速度数学模型,提出杆臂效应补偿算法,并以速度 + 姿态匹配传递对准方法为例,利用计算补偿方法对杆臂速度项进行补偿,减弱杆臂效应对传递对准精度的影响,最后通过仿真验证了该模型可以有效的提高对准精度和对准时间。
Abstract: The Transfer Alignment is an effective method of improving the initial alignment velocity and accuracy of inertial navigation system, and the lever-arm effect is an important factor affecting the accuracy of transfer alignment. The paper analyzed the reasons for the formation of the lever-arm effect, proposed an compensation algorithm for the lever-arm effect, built the mathematical model of velocity and acceleration, took a method of velocity and position matching in transfer alignment, used the method of calculating the compensation to compensate the lever-arm velocity, and diminished the effect of the lever-arm effect on the transfer alignment accuracy. Finally, the simulation shows that the model can effectively improve the alignment accuracy and alignment time.
