Many results in attitude analysis are still meaningful when the attitude is restricted to rotations about a single axis. Such a picture corresponds to attitude analysis in the Euclidean plane. The present report formalizes the representation of attitude in the plane and applies it to some well-known problems in a two-dimensional setting. In particular we carry out a covariance of a two-dimensional analogue of the algorithm OLAE, recently proposed by Mortari, Markley, and Junkins for optimal attitude determination.

平地中的态度分析：平面真相

当将姿态限制为围绕单个轴旋转时，姿态分析中的许多结果仍然有意义。这样的图片对应于欧几里得平面中的姿态分析。本报告正式确定了飞机上姿态的表示形式，并将其应用于二维环境中的一些众所周知的问题。特别是，我们进行了OLAE算法的二维类似物的协方差，该算法最近由Mortari，Markley和Junkins提出，用于确定最佳姿态。
