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.

Note that the Eclipse Summary data provider reports the start and stop times of penumbra which, if umbra exists, occur before and after umbra, respectively. This means that if the Eclipse Summary is generated in cases when it starts in umbra, then the start of penumbra is reported as "No Data" because it occurred prior to the start of reported data. |
| Eclipse Times | Generates a listing of all eclipse events. Eclipsing events are start and end of periods of partial lighting (penumbra) and periods of zero lighting (umbra). |
| Ephemeris Diff | The relative ephemeris of the assigned object with respect to the primary object, as observed from the requested coordinate system, expressed in Cartesian components as a function of time. The relative velocity vector is computed as observed in the requested coordinate system, and expressed in components of that frame. |

| Flight Attitude | Attitude of the body axes, expressed using standard aeronautical terms. |

This data provider is only available for Aviator propagated vehicles. |

| Lighting Times | Generates a listing of all lighting events. Lighting events are start and end of periods of full lighting (sunlight), partial lighting (penumbra) and periods of zero lighting (umbra). Note that the Lighting Times data provider reports all computed penumbra intervals, which means that if umbra exists, then two penumbra intervals, each with its own start and stop times, is reported--one before and one after the umbra interval. So, if lighting times that start in umbra are generated, then the first reported penumbra interval corresponds to the times that follow after the first umbra, and the penumbra interval prior to the first umbra is not reported. |
