Attention: Office of Engineering and Technology
RE: Request for Special Temporary Authority

Dear Ms. Dortch,

        Intelsat LLC herein requests a grant of Special Temporary Authority from
February 15, 2004 through March 15, 2004 to conduct certain tests,
demonstrations and experiments described below using a 1.0 meter Ku—band
antenna in conjunction with Intelsat‘s Washington, D.C. E010104 earth station and
the Intelsat satellite at 325.5 degrees E.L. The tests need to begin on that date in
order to take advantage of available satellite time and to accommodate the
requirements of the scientists and engineers needed to perform the testing.
       In brief summation, the test earth station, a VSAT, will be used to validate
the performance of a system which leverages the cable modem networking
standard called DOCSIS (Data Over Cable Service Interface Specification). Coupled
with advanced satellite waveforms, this technology will lower the cost of consumer
terminals, reduce satellite bandwidth requirements, enable easy self—provision for
customers, and provide mature customer service, billing and network control
software to network providers.
       The 1.0 meter antenna will be located on the same site as E010104. It will
operate using the same 14.0—14.5 GHz transmit band and 10.95—11.2 GHz and
11.45—12.2 GHz receive bands licensed for EO10104. The radio frequency analyses
associated with that license shows that there will be no harmful radiofrequency
interference into any other lawfully operating earth station. In the extremely
unlikely event that interference should occur, Intelsat LLC will cease operations
immediately. Intelsat LLC agrees to accept any interference in the downlink
frequency band. Technical information related to this antenna is attached hereto.


        A grant of Special Temporary Authority, as requested herein, will further the
development of satellite communications technology in furtherance of the public
interest. If there are any questions regarding this request, please contact Robert
Mansbach at 202—944—7891.


                               Respectfully submitted,
                                     Intelsat LLC

  The Channel Master® Type 100 Tx 1.0m Offset Rx—Tx Antenna is a rugged commercial grade
  product suitable for the most demanding applications. The reflector is thermoset—molded for
  strength and surface accuracy. Molded into the rear of the reflector is a network of support
  ribs which not only strengthens the antenna, but also helps to sustain the critical parabolic
  shape necessary for transmit performance.Reflectors are available with hydrophobic coating
  for use in areas where snow buildup is a problem.

  The Az/El mount is constructed from heavy—gauge steel to provide a rigid support to the
  reflector. The Az/El mount secures the antenna to any 2.88—3,00 in. O.D. mast and prevents
  slippage in high winds. A specially formulated powder paint process offers excellent protection
  from weather—related corrosion.
