Missile: Swath Points: 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.

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.
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.
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 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.
