| 摘 要： | 高速、高速度的圆锥偿补算法是提高捷联惯性导航系统（ＳＩＮＳ）性能的重要环节。本文对Ｃｈａｎ Ｇｏｏｋ Ｐａｒｋ等提出的新圆锥补偿方法进行了进一步的研究。文中给出了经典圆锥运动的角速度模型，推导出了经典圆锥运动的角增量公式、角增量叉乘公式、圆锥补偿系数方程和误差公式，并将该方法拓展至利用前一圆锥补偿周期角增量和的圆锥补偿算法。

| Abstract: | High speed and high accuracy coning algorithm plays a key role in strapdown inertial navigation system(SINS).In this paper,a furthur research on coning algorithm is made using the new approach proposed by Chan Gook Park.The angular veloclty modle is given at first,then the incremental attitude vector,the cross product of two incremental attitude vector,the equation of coning compensation coefficients and the error equation are derived.Based on this method,a new coning compensation algorithm is given.In the end some examples are given to test the results. |
