| Name | Description |
|---|---|
| FlightPath | XY plane of the FlightPath coordinate system which is a plane passing through the object's center that contains its flight direction and is constrained to be as parallel as possible to the central body surface. |
| FlightSymmetryPlane | XZ plane of the FlightPath coordinate system which is a plane passing through the object's center that contains its flight direction and its surface normal. |
| LocalHorizontal | XY plane of the Topocentric coordinate system which is a plane passing through the object's center that is parallel to the central body surface and is aligned with it. |
| SEET_GeomagneticEquator | The plane containing the geomagnetic field equator. Its normal is the geomagnetic north pole. |
