Aircraft: LLA State: Fixed

A coordinate system attached to the central body and rotating with it. The z-axis is nominally along the rotation axis.

Name Dimension Type Description
Time DateFormat Real Number Time.
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.
Alt DistanceUnit Real Number The altitude value (i.e., magnitude of the relative position vector between the object and its detic subpoint).
Alt AGL DistanceUnit 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 AngleRateUnit Real Number The rate of change of the detic latitude.
Lon Rate AngleRateUnit 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 LatitudeUnit Real Number The centric latitude (i.e., angle between the detic subpoint's position vector and the XY plane).
Centric Lon LongitudeUnit Real Number 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 DistanceUnit 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 DistanceUnit 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 DistanceUnit Real Number The easting value within the UTM zone for the detic subpoint. Available only when the central body is Earth.
UTM Northing DistanceUnit 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.
