| Description: The rotation_direction attribute identifies the direction of the rotation for a specific quaternion. This is used when the two frames involved are unambiguously identifed in the enclosing classes. |

| Permissible Value(s) | Value | Value Meaning |
| | Forward | Reference frames are generally defined sequentially from a base reference frame (e.g., base frames might be ICRF, IAU Mars, or the landing site from which a rover begins its exploration). rotation_direction = Forward corresponds to rotation in the 'direction' from the base frame. |
| | From Base | Reference frames are generally defined sequentially from a base reference frame (e.g., base frames might be ICRF, IAU Mars, or the landing site from which a rover begins its exploration). rotation_direction = Away From Base corresponds to rotation in the 'direction' from the base frame. |
| | Present to Reference | The quaternion rotates the frame identifed by Coordinate_Space_Present to the frame identified by Coordinate_Space_Reference. |
| | Reference to Present | The quaternion rotates the frame identifed by Coordinate_Space_Reference to the frame identified by Coordinate_Space_Present. |
| | Reverse | Reference frames are generally defined sequentially from a base reference frame (e.g., base frames might be ICRF, IAU Mars, or the landing site from which a rover begins its exploration). rotation_direction = Reverse corresponds to rotation toward the base frame. |
| | Toward Base | Reference frames are generally defined sequentially from a base reference frame (e.g., base frames might be ICRF, IAU Mars, or the landing site from which a rover begins its exploration). rotation_direction = Toward Base corresponds to rotation toward the base frame. |
