LLA State Variants | Data Provider Groups | Data Provider Elements

LLA State

The ephemeris of the object, expressed in LLA elements, as a function of time. The coordinate system is the Fixed frame of the object's central body.

Data Provider Variant: Vehicle

Available for these objects: Aircraft, GroundVehicle, LaunchVehicle, Missile, Satellite, Ship

Type: Time-varying data.

Availability: Reports | Graphs | Dynamic Displays | Strip Charts

Data Provider Groups

Name	Description
TrueOfDateRotating	A variation of the Fixed system where pole wander is ignored. The equator is the same as the TrueOfDate equator and the frame spins about the TrueOfDate z-axis.
Fixed	A coordinate system attached to the central body and rotating with it. The z-axis is nominally along the rotation axis.

Data Provider Elements

Name	Dimension	Type	Description
Time	Date	Real Number or Text	Time.
Lat	Latitude	Real Number or Text	The detic latitude (i.e., angle between the detic subpoint's surface normal vector and the XY plane.).
Lon	Longitude	Real Number or Text	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.
Alt	Distance	Real Number	The altitude value (i.e., magnitude of the relative position vector between the object and its detic subpoint).
Alt AGL	Distance	Real Number or Text	The altitude above ground level. The difference between the altitude and the terrain altitude. If no terrain is found at the detic subpoint, then the string "No Terrain" is returned.
Lat Rate	AngleRate	Real Number	The rate of change of the detic latitude.
Lon Rate	AngleRate	Real Number	The rate of change of the detic longitude.
Alt Rate	Rate	Real Number	The rate of change of the altitude value.
Centric Lat	Latitude	Real Number or Text	The centric latitude (i.e., angle between the detic subpoint's position vector and the XY plane).
Centric Lon	Longitude	Real Number or Text	The centric longitude (i.e., angle from the X-axis locating the projection of the detic subpoint's position vector onto the XY plane).
Terrain Alt	Distance	Real Number or Text	The terrain altitude. The altitude of the terrain located at the detic subpoint's latitude and longitude, measured from the object's central body surface along the surface normal through the detic subpoint. If no terrain is found at the detic subpoint, then the string "No Terrain" is returned.
Alt MSL	Distance	Real Number or Text	The altitude above mean sea level. The difference between the altitude and the height of mean sea level, measured from the object's central body surface along the surface normal through the detic subpoint.
UTM Zone	Unitless	Text	The UTM Zone character indicator for the detic subpoint. Available only when the central body is Earth.
UTM Easting	Distance	Real Number	The easting value within the UTM zone for the detic subpoint. Available only when the central body is Earth.
UTM Northing	Distance	Real Number	The northing value within the UTM zone for the detic subpoint. Available only when the central body is Earth.
MGRS Cell	Unitless	Text	The MGRS (Military Grid Reference System) code for the cell area containing the detic subpoint. Available only when the central body is Earth.
