The horizon point on the left side of
the horizontal component of velocity vector. The velocity vector is
measured as observed from the object's central body fixed
coordinate system. The horizontal component is that component not
along the detic zenith of the object.

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. |
| Rad |
DistanceUnit |
Real Number |
The radius value (i.e. magnitude of the position
vector). |
| Elevation |
AngleUnit |
Real Number |
Angle between the velocity vector and the local
horizontal plane. The velocity vector is the velocity of the
object, as observed in the object's central body fixed coordinate
system. |
| Half Angle |
AngleUnit |
Real Number |
The angle between the surface normal at the detic
subpoint of the object and the relative position between the object
and swath point. |
| Distance |
DistanceUnit |
Real Number |
Distance between the center of the reference plane
and the projection of the selected point onto the reference
plane. |

The value is "Side" if the swath type is Ground
Elevation, Vehicle Half Angle, or Swath Half Width. The value is
"Envelope" if the swath type is Ground Elevation Envelope or
Vehicle Half Angle Envelope if the left/right swath point exists;
if it does not, the value is "Side" and the left/right swath point
being reported at that time uses the Ground Elevation or Vehicle
Half Angle setting (as appropriate) to compute its value. |
| 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. |
