Browse and Interrogate ITU Database Files

For visual browsing of ITU space database files, intersystem interference calculation, intersystem frequency overlap analysis and frequency coordination support

Sat-Coord can be used to interrogate and retrieve information from the ITU database files (including the SRS, IFIC and backlog) quickly and accurately. Search criteria can be defined to retrieve just the information you need, and the results can be exported to any text or csv compatible application.

In order to best describe the features that Sat-Coord offers, a few examples of searches which can be performed with the software are shown below, but bear in mind that searches from within Sat-Coord are completely freeform in nature meaning you can start with any search, and perform any search from this.

Simple Searching

In the example shown to the right a satellite network has been chosen (AGRANI-2) and it has been examined for its orbital position, and then the notification reason.

This is a code which returns the type of filings which have been made for that network - the results A and C refer to advanced publication and coordination request.

From the coordination request we have searched for the regulatory date of receipt - this is a very important date which denotes the "priority" of a filing.

Then from one of these dates we have searched for the exact frequency ranges filed.

Such a search can be useful to either quickly identify the bands filed for a particular network to be coordinated, or the priority status of a filing, or even the parts of a filing which have an unfavourable finding.

It can be quickly seen here which bands the network has filed for coordination, and the date of protection status of the filing.

Custom Searching

In the second example shown to the right a much more complex search has taken place - we have searched for all networks with which coordination may be required by the network identified above in the Ku-Band.

We have searched for the orbital position and satellite network name of any filing in the SRS which meets the following criteria:

Has an orbital position between 42°E - 62°E
Has filed Ku-Band transponders
Has a regulatory date of receipt of 15/02/1995 or earlier

As can be seen we can then perform any further searches we wish on the results. We have searched for the exact filed frequencies of one of the identified networks, and then the beam name under which this frequency has been filed.

We can construct "custom searches" such as the one above to only retrieve the exact information we need. These can be very complex indeed - finding specific frequency ranges, or emission codes for example. You can also specify as many criteria as you need to make up the search.

IFIC Processing

In this example a similar search has been performed to the search above, but this time it was performed on the bi-weekly IFIC (International Frequency Information Circular) database files.

Using such a search we can quickly identify any new networks which have the ability to cause our networks interference. This is a very important process since the networks must be identified and informed in order to avoid losing priority over these networks.

It can be seen that we have asked for the search to output the orbital position and network name of the networks identified, but any information can be output.

We can also perform any subsequent searches we wish on the data identified.

The "no results" output indicated that no networks were found matching the data requested.
