Federal Communications Commission (FCC), IEC plans to use this Ku Band system to communicate with Intelsat Americas 5 (IA—5), which is located at 97 degrees west longitude. Your company operates the Brasilsat Bd, located at 92.00 degrees west longitude. As your satelliteis within 6 degrees of IA—5, the FCC requires we obtain an affidavit from you on our proposed system. You have the ight o reply to the enclosed material and may reply directly to the FCC, citing the above file number. If you do not reply within thirty (30) calendar days from the date of this notice, he FCC will construe your lack of reply as an assent to the grant of IEC‘s earth station application: Sincerely, Z ce.

Navy TRIDENT test programs IEC opertesKu—band satlite network to fiiltate th transfr ofestdata. IEC porchases two diffrentbandwidth services boh in the Ku—hand spectrum from TelecommunicationsIiternatonal Inc., a bandwidth rescllr.IRC network architecture consitofsix temporay—fxed 24 meter Ku—band (14.0 — 14.6 GHf) eart sttions (VSATs) and two Earth Suitions on abourd Vesl (ESV) — on temporary—fixed 2.0 meter and one temporary—fzed 24 metr. ESVar locted on aboard the USNS WATERS, which operate at leat 100 miles offUnted Sttes Consline in Atlantc or Pacfc Oceans during thee tess, Thefist leased srvice s nonreemptble ane megiberts offllime transponder bandwidth and th second is a 4.5—megahertsofoccasional use transponder bandwidis.
