Conclusions
ITU Software Tools
The ITU is responsible for the publication and registration of satellite networks filed by administrations. 

To support this work the ITU produces a number of software tools available for download and/or purchase via the ITU’s web site (see here). 

Some of these are available to public users, others need ITU "TIES" password (limited).

ITU Space Radiocommunications Stations Database (SRS)
This database is a subset of the MIFR dealing with all space networks.

It is available online via the SNS online system, updated daily. It is also available on CD-ROM - SRS CD-ROM, published every six months. Also a weekly CD-ROM of new networks added to the database, called the International Frequency Information Circular (IFIC) is available.

ITU SNS Online
Access to the online data can be found here.

It gives access to:

  • Published networks (i.e. those with regulatory "status")
  • Pre-publication networks (i.e. those as yet without regulatory "status", for information)
  • Regulatory information - "Priority" date, regulatory findings, coordination requirements
  • Technical information -Network technical parameters for use in analyses
ITU SpaceQuery
SpaceQuery software offers similar functionality to the SNS Online system. It is a CD-ROM based database tool. It allows a user to query and extract information from the SRS database.
ITU GIMS
GIMS - "Graphical Information Management System".

This software allows access to and viewing of (as well as creation of new) satellite beam footprint diagrams. It can be used linked with SpaceQuery or in a stand-alone mode.

The API is published so can be integrated with your own software.

Other ITU Tools
ITU has a number of other tools:

Data management tools:

  • SpaceCap – Creates new network databases
  • SpacePub – Prints network databases in publication format

Data analysis tools:

  • APP29 – Article S8 analysis
  • MSPACE – Interference analysis (mainly for plans)

Next: Section 6 - Proprietary Software Tools
