The backlog in satellite network filing has been steadily growing for a number of years and the BR estimate that, even if no further submissions were made, it would take three years work to clear. This backlog threatens to undermine the international satellite network filing process and imposes limitations on the ability of administrations and satellite operators to respond to changing requirements in radiocommunications. Over the past few years administrations and the BR have expressed a number of opinions on the reason for this backlog and how it can be reduced.
