This paper presents a new method named "Analytic Orthogonalization", for orthogonalizing direction cosine matrix.

本文提出方向余弦矩阵正交化的一种新方法——解析正交化。

Since it involves no procedure of orthogonalization, the method makes calculation much simpler than that of conventional ones.

可以避免计算较繁的正交化过程，以使计算简便。

The Successive Orthogonalization Decentralized Kalman Filter (SODKF ) is a new method which is used for large system state estimation.

逐次正交化分布式卡尔曼滤波器是对大系统进行状态估计的一种新方法。
