IEC plans to use this Ku Band system to communicate with Intelsat Americas 5 (IA—5), which is located at97 degrees west longitude. Your company operates the AMCI, located at 103.00 degrees west longitude. As your satellie is within 6 degrees ofIA—5, the ECC requires we obtain an affidavit from you on our proposed system. You have the right to reply to the enclosed material and may reply directly to the FCC, citing the above file number. If you do mot reply within thirty (30) calendar days from the date ofthis notice, the ECC will construe your lack ofreply as an assent to the grant of IEC‘s earth station application. Sincerely, cc.
