Orientation Field
This field defines the rotation from the factory to user axis sets. This rotation is relative to the default factory
orientation (connector aft, base plate down). The default factory axis set is (Ux, Uy, Uz) defined by the connector
pointing in the –Ux direction and the base plate pointing in the +Uz direction. The user axis set is (X, Y, Z) as defined
by this field. An example of the factory axis set is shown below:
