Facility/Place/Target: LLR State
The ephemeris of the object, expressed
in LLR elements, as a function of time. The ephemeris can be
requested in a variety of coordinate systems. The available
coordinate systems depend on the object's central body. Nominally,
the systems Fixed, Inertial, J2000, TrueOfDate, and MeanOfDate are
supported, although some central bodies (notably the Earth and Sun)
have more. The following lists the systems available for
Earth.

Description |
| Lat |
LatitudeUnit |
Real Number |
The detic latitude (i.e., angle between the detic
subpoint's surface normal vector and the XY plane.) |
| Lon |
LongitudeUnit |
Real Number |
The detic longitude (i.e., angle from the X-axis
locating the projection of the detic subpoint's surface normal
vector onto the XY plane.) Longitude increases in the direction
found using the right-hand rule about the Z-axis. |
| Rad |
DistanceUnit |
Real Number |
The radius value (i.e. magnitude of the position
vector). |
