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.

Type: Fixed data

NameDimensionTypeDescription
LatLatitudeUnitReal NumberThe detic latitude (i.e., angle between the detic subpoint's surface normal vector and the XY plane.)
LonLongitudeUnitReal NumberThe 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.
RadDistanceUnitReal NumberThe radius value (i.e. magnitude of the position vector).
