Since the orbital motion is planar, one can fix the position and velocity by defining the plane of the motion, and then specifying the two‐dimensional (perifocal) position and velocity in the orbital plane. This chapter is devoted to the representation of a coordinate frame's orientation by a set of kinematical parameters, which is useful in fixing the orbital plane. The simplest coordinate transformation is a rotation about one of the axes of a given coordinate frame, and is called an elementary rotation. In the elementary rotation of the coordinate frame, the Euler axis is aligned with one of the axes of the original frame, thereby producing no change in the corresponding axis of the transformed frame. The methods of coordinate transformation due to rotation can be applied to resolving the orbital motion in a reference frame firmly attached to a rotating central body, such as a planet.
