Your company operates the Galaxy 11, located at 91.00 degrees west longitude, the Galaxy 3C, located at 95.00 degrees west longitude and the Galaxy 4R, located at 99.00 degrees west longitude. As your satellte is within 6 degrees of IA—5, the FCC requires we obtain an affidavit from you on our proposed system. You have the rightto reply tothe enclosed material and mayreply directly to the FCC, citing the above file number. If you do not reply within thirty (30) calendar days from the date ofthis notice, the FCC will construe your lack of reply as an assent to the grant ofIEC‘s earth station application.
