摘　　要：在环境恶劣情况下,捷联惯导系统存在较为严重的圆锥误差效应,想要进一步提高算法的精确度必须对圆锥误差进行补偿。在圆锥运动的条件下,根据对经典的圆锥误差研究方法,利用三角变换公式将补偿效果相同项进行拆分合并,得到了新的求解圆锥误差补偿系数的算法,并给出了求解的一般公式,为以后对圆锥补偿算法优化提供了一个新的参考模型。通过验证可以证明算法的正确性。The coning error of the strapdown inertial navigation system(SINS)has serious coning error effect in bad environment,so it is necessary to compensate the coning error to improve the accuracy of the algorithm.Under the condition of conical motion,according to the classical conical error research method,the trigonometric transformation formula is used to split and merge the items with the same compensation effect,and a new algorithm for solving the conical error compensation coefficient is obtained,the general formula for the solution is given.A new reference model is provided for the future optimization of the compensation algorithm.The correctness of the algorithm can be proved by verification.
