| 摘 要： | 为了能将新型固态速率陀螺应用在常规弹箭上，必须研究超高精度的捷联航姿算法，以适应此特殊的应用环境．应用速率陀螺在当前迭代周期和前次迭代周期内输出的信息提出一种修正算法，推导了该方法在典型圆锥运动下的算法误差．结果表明：在速率输入情况下，与传统算法比较，新算法具有较高的精度和适中的计算复杂度．

| Abstract: | The new type solid state gyro exports angular rate signals directly.Classical rotation vector attitude algorithms have to integrate angular rate frequently.In this paper,by utilizing the angular rate singals export by rate gyro from the latest and current update periods,a new strapdown attitude algorithm expression is developed and the error of the algorithm under the coning motion is derived too.Simulation results show that,compared to the conventional algorithms,the accuracy of the new algorithm is better and calcuation complexity is moderate. |
