摘要
传统的 SITA N算法是利用相对高度之差作为卡尔曼滤波器量测值的 ,文中提出并证明了在 SITA N算法中 ,可以采用绝对高度之差或地形高度之差作量测值 ,量测值的不同选取对滤波结果没有影响。
In the traditional SITAN algorithm, the difference of relatively altitudes is acted as the measurements in Kalman filter. This paper proves the difference of absolute altitudes or terrain altitudes is able to be acted as the measurements. It is concluded that different selection of measurements in Kalman filter has no effects on consequences in SITAN terrain auxiliary navigation.
