Attitude YPR
The attitude of the vehicle with respect to the vehicle's central body inertial coordinate system, expressed using YPR angles.Similar to Euler angles, YPR angles specify attitude using three rotations in sequence: a rotation about the reference X axis is called roll (R), a rotation about the reference Y axis is called pitch (P), and a rotation about the reference Z axis is called yaw (Y). Unlike Euler angles, the rotations are not made about axes defined by an earlier rotation: each rotation is made about the reference system's axes.
As used in YPR angles, the names yaw, pitch, and roll do not refer to the angles normally used in aviation; the terms yaw, pitch, and roll in aviation refer to 321 Euler angles.
