  4.  
  5. In a right-handed Cartesian 3D plane, with North being parallel to the y-axis, the relative position of a target can be defined by the following terms:
  6.  
  7. 1. Target X: TargetDistance*cos(TargetElevation)*sin(TargetHeading)
  8. 2. Target Y: TargetDistance*cos(TargetElevation)*cos(TargetHeading)
  9. 3. Target Z: TargetDistance*sin(TargetElevation)
  10.  
  11. In the SP coordinate system, these correspond to:
  12.  
  13. 1. X: Latitude
  14. 2. Y: Longitude
  15. 3. Z: Altitude
  16.
