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

!!!! NEW !!!! in - GIMS 3.4

• You should install this version to profit from
  the GIMS reference database incremental update
  that have been started as of IFIC
  2504/07.10.2003.
•  
• To make sure the reference database may be
  updated, you should install it locally. This
  option is proposed during the GIMS installation
  program.

24
How does it work? (1)

• As you may already have experienced, even if you
  work with a local copy of REFDB it is
  automatically updated with the latest data found
  either on SRS or IFIC CD-ROMs. The same ease of
  use will be provided with the incremental update
  database.
• Once REFDB is configured to be local, the
  incremental update procedure is started
  automatically whenever you open REFDB and an IFIC
  CD-ROM is in the CD reader. GIMS checks whether
  an incremental update database is available and
  whether there are new update actions to be
  performed.

25
How does it work? (2)

• The incremental update database gets bigger on
  every IFIC CD because it contains all updates to
  be performed in between two releases of the SRS
  CD-ROM. This way you can just use the latest IFIC
  CD available to make your REFDB copy up-to-date.
  After a new SRS CD release, the incremental
  update database is cleared and will be filled
  again until the next SRS CD.
• Troubleshooting
• I get error messages like Out of memory or No
  valid reference databases were found in the
  master folder"
• You may get these messages when you do not work
  with a local copy of REFDB and an IFIC CD with an
  incremental database in the master folder has
  been detected. To correct the problem, change the
  REFDB settings so that you work with a local copy
  of REFDB.
