Quaternion The first three elements form the vector part of the quaternion, the fourth is the scalar element. Defined as:

where e1, e2, e3 are the three elements of the Euler rotation axis (unit vector) and phi is the Euler rotation angle. The quaternion represents the coordinate transformation from frame A to frame B.
Q=[Q1,Q2,Q3,QC] N/A, N/A, N/A, N/A 1.3.112.4.X.8.1
Quaternion Derivative Rate of change of the quaternion. 1/s 1.3.112.4.X.8.2
Angular Velocity The rotational rate of frame B with respect to frame A. The vector direction is the instantaneous axis of rotation of frame B with respect to frame A and the vector magnitude is the instantaneous rate of this rotation. The subscript indicates the frame in which the angular velocity is resolved. 'SC' refers to the spacecraft body frame. radians/second 1.3.112.4.X.8.3
