Graphical Interference Management System I

• Gain tool interpolates gain at any location on
  the earth
• Contour generation using interpolation (nice with
  3db ellipse)
• PFD examination produces list of affected
  countries
• Appendix 30, Article 21

21
Graphical Interference Management System II
Get the gain by clicking on the map Result in
status bar
Calculate Gain at given coordinates Generate a
contour of a given gain
22
Graphical Interference Management System III
Contour generation
Elliptical beam (-3dB ellipse)
-2, -4, -6, -8, -10, -20 dB contours
Antenna Pattern
Also for shaped beams using interpolation
