Swath Points

The location of the object's horizon on the central body surface that is to the side of the motion of the object, reported as left and right horizon points over time.

For the Ground Elevation Envelope or Vehicle Half Angle Envelope swath types, the left/right swath point may not exist. If it does not, the point being reported at that time uses the Ground Elevation or Vehicle Half Angle swath setting as appropriate.

Name	Description
Left Swath	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.
Right Swath	The horizon point on the right 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.

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.
Rad	Distance	Real Number	The radius value (i.e. magnitude of the position vector).
Elevation	Angle	Real Number or Text	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	Angle	Real Number or Text	The angle between the surface normal at the detic subpoint of the object and the relative position between the object and swath point.
Distance	Distance	Real Number	Distance between the center of the reference plane and the projection of the selected point onto the reference plane.
PointType	Unitless	Text	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	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.
