      Subject: Engineering Certification of SES Americom, Inc. for the AMC—15 Satellite



      To whom it may concern,

      This letter confirms that SES is aware that Thales Avionics, Inc., licensed by the Federal
      Communications Commission ("FCC") as Thales Avionics, Inc. ("Thales"), is seeking FCC a blanket
      authorization to operate technically identical conventional Ka—band transmit/receive remote terminals
      pursuant to ITU RR 5.526 and the Commission‘s current framework for the Ka band. Thales seeks
      authority for Thales Avionics, Inc.‘s new remote terminals to communicate with the AMC—15 satellite at
      105° W.L., according to the Commission‘s precedent for Ka band aeronautical applications.

      Based upon the contents of the application (we understand that Thales will seek a new blanket
      authorization) and the representations made to SES by Thales concerning how it will operate on
      AMC—15 according to its letter dated February 10, 2017:


            e   SES certifies that it has completed coordination as required under the FCC‘s rules and that
                the power density levels specified by Thales are consistent with any existing coordination
                agreements to which SES is a party with adjacent satellite operators within +/— 6 degrees of
                orbital separation from AMC—15.

            *   If the FCC authorizes the operations proposed by Thales, SES will include the power density
                levels specified by Thales in all future satellite network coordination with other operators of
                satellites adjacent to AMC—15.

      SES has also reviewed the discussion in the applications regarding the off—axis EIRP density of
      Thales antennas communicating with AMC—15 in directions other than along the GSO plane. SES is
      of the view that the non—compliant emissions would not create interference to Ka—band geostationary
      satellites.

      YoursISincerely,,              ,
