As ESOC currently operates three satellites at the 61.5º W.L. nominal orbital location and has a pending application to launch a satellite to that nominal orbital location, this move is relevant to the interference environment described in the above-referenced applications. With the move of DIRECTV 1R, the closest non-ESOC-owned satellite is now Nimiq 5, which is located at 72.7º W.L. Nimiq 5 is both further than DIRECTV 1R was from 61.5º W.L. and is fully leased for use by an ESOC affiliate. The DIRECTV 1R move, therefore, only improves the interference environment at the 61.5º W.L. nominal orbital location as described in the above-referenced applications. If you have any questions regarding the information described in this letter, please contact me. Respectfully submitted, _________/s/___________ Stephanie A. Roy Counsel for EchoStar Satellite Operating Corporation
