Your company operates the Inmarsat 2 F2, located at 98.10 degrees west longitude. As your satellte is within 6 degrees of A—5, the FCC requires we obtain an affidavit from you on our proposed system. You have the right to reply to the enclosed material and may reply diectly to the FCC, citing the above file number. If you do not reply within thity (30) calendar days from the date ofthis notice, the FCC will construe your lack ofreply as an assent to the grant of IEC‘s earth station application. Sincerely, ce.
