The Bureau draws your attention to resolves 6 of Resolution 55 (WRC-2000), which encourages Administrations to submit all graphical data in a format compatible with the BR data capture software (GIMS). Although it will still be possible to submit diagrams in paper format, as provided for under resolves 6 of Resolution 55 (WRC-12), administrations are urged and encouraged to make use of the electronic GIMS mdb format whenever possible so that they can benefit from the improved version of the software tools before submitting their satellite network filings to the Bureau.
From 01 January 2013, the only receivable electronic format for submission of graphical information is GIMS mdb. GIMS GXT files are not receivable.
For more details please see CR 337.
