5Incremental Update
- Update Database
- All modifications done in the past two weeks
- Not related to the SNS increment.
- Why updating?
- Get the latest data
- Keep SNS/SPS synchronized with GIMS
- Important for GIBC and MSPACE.

18Data Capture What you cant do
- Design your antenna !
- View GIMS as a SpaceCap equivalent for graphical
data. - Change the contour shape interactively.

24Interference
25Interference The Big Picture
- 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
26Interference - Gain
Get the gain by clicking on the map Result in
status bar
Calculate Gain at given coordinates Generate a
contour of a given gain
27Interference Contour Generation
Elliptical beam (-3dB ellipse)
-2, -4, -6, -8, -10, -20 dB contours
Antenna Pattern
Also for shaped beams using interpolation
28Interference - PFD
PFD Tool Click on map to get PFD
Access to input data dialog box
PFD Value at Point
PFD contour List of affected countries
Data required for PFD analysis e.g. maximum
gain, power
