central body and rotating with it. The z-axis is nominally along
the rotation axis.

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). |
| 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. |
