What Cant You Do With GIMS ?

• Design your antenna !
• View GIMS as a SpaceCap equivalent for graphical
  data.
• Change the contour shape interactively.

Graphical Interference Management System

• 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

18
Get the gain by clicking on the map Result in
status bar
Calculate Gain at given coordinates Generate a
contour of a given gain
19
PFD Tool Click on map to get PFD
Access to input data dialog box
PFD contour List of affected countries
Data required for PFD analysis e.g. maximum
gain, power
