摘要
分析了导弹在高动态环境下捷联惯导系统圆锥误差形成因素及原因，从理论上对各种因素进行了误差的定量推理与对比，指出不能正确感测运载体的角运动和姿态更新率过低是引起圆锥误差的最重要因素。
It is analyzed that how the coning error of SINS in high dynamic environment occurs. Some important factors that influence the coning error are compared. It points out that the error sensing of coning motion and low attitude updating rate are the most important factor of the coning errors.
