| 摘 要： | 为了对惯导系统空中动基座对准精度进行评估 ,文中提出了逆序递推滤波算法 ,利用对准结束后一段时间的主从惯导系统的导航数据 ,通过一次卡尔曼滤波运算 ,便可求出对准误差。经飞行实验结果处理证明 ,该方法有效 ,具有工程应用价值

| Abstract: | This paper presents a backward recursive fi ltering algorithms to improve the estimate accuracy of in-flight moving base ali gnment for inertial navigation system. After alignment, using Kalman filtering a lgorithm the alignment error is obtained. Flight experiments show this method is effective, and has engineering application value. < |
