                                             ISAT US Inc.
                                         FCC Form 312 Exhibit A

                                  Application to Modify License E150097

 I.            DESCRIPTION OF MODIFICATION

               ISAT US Inc. (“ISAT US”) hereby seeks to modify its Global Xpress (GX) Ka-band

      blanket earth station license, Call Sign E150097 (“License”), File No. SES-LIC-20150625-

      00383 (“GX Land Application”) (as modified), to add two new GX Earth station terminal types,

      Panther II 60 and Panther II 96, which will communicate with the Inmarsat-5 F2 (“I5F2”) and

      Inmarsat-5 F3 (“I5F3”) satellites. Section II addresses the proposed new Earth station terminals.

      No other changes are requested by this modification application. ISAT US incorporates by

      reference Exhibits F (response to Question E17 regarding the remote control point) and G (24-

      hour point of contact)1 of the GX Land Application, as well as certain other portions of the GX

      Land Application referenced below.

II.            NEW EARTH STATION TERMINALS

               This modification application seeks to add two terminal models that are manufactured by

      L3 GCS. These are the Panther II 60 and Panther II 96 terminals, which employ 60 centimeter

      and 96 centimeter antennae, respectively. The terminals will operate on the same frequencies as

      the GX Terminals in the current license: 19.7-20.2 GHz (space-to-Earth) and 29.5-30.0 GHz

      (Earth-to-space). The terminals will operate at fixed or temporary fixed locations and allow

      professional personnel from organizations from various sectors, initially U.S. government and

      potentially including in the future media and humanitarian, to quickly deploy a communication

      network to meet mission needs.

          Exhibit G was submitted as a supplement to the GX Land Application on August 14, 2015.


      A. Land Terminal Description

           This application seeks to license the Panther II 60 and Panther II 96 terminals. The

    terminals will operate on the same frequencies as the GX Terminals in the current license:

    19.7-20.2 GHz (space-to-Earth) and 29.5-30.0 GHz (Earth-to-space). As illustrated in the

    off-axis EIRP spectral density plots in Exhibit B, the L3 GCS terminals meet the performance

    requirements in Section 25.138 (a) under clear sky conditions. Additionally, each of these

    terminal types will be operated within the -118 dBW/m2/MHz power flux-density at the

    earth’s surface of the I5F2 and I5F3 satellite. Thus, the proposed terminals are able to

    operate without causing unacceptable interference, consistent with the requirements of

    Section 25.209(f).2

           The Commission has deleted the requirement to provide receive earth station patterns in

    the 19.7-20.2 GHz frequency band (see Sections 25.132 and 25.115). To the extent that the

    proposed terminal may have minor exceedance at certain off-axis angles Inmarsat understands

    and agrees to accept interference from adjacent FSS satellite networks to the extent the relevant

    receiving antenna performance requirements of Section 25.209 are exceeded.

           Radiation hazard analyses for the L3 GCS Panther II terminals and a discussion of the

    results are provided in Exhibit C.

           The proposed terminals will be subject to the same national security requirements

    described in Section 4 of the GX Land Application. That discussion is incorporated by

    reference herein.

          The following sections provide a description of each of the terminal types.

    See Section 25.209(f).


   B. Panther II 60 Terminal

       The required technical data for the proposed Panther II 60 earth station is provided in the

Form 312. This terminal type employs a 60 centimeter antenna and the half-power beamwidth

required in Section 25.130(f) is 1.1 degrees. In addition, for blanket licensing of transmitting

Earth stations in the 29.5-30.0 GHz band, the Commission adopted off-axis EIRP spectral density

levels contained in Section 25.138(a). As illustrated in the off-axis EIRP spectral density plots

in Exhibit B, the proposed terminal type meets the performance requirements in Section 25.138

(a) under clear sky conditions.

       Below is an image of the Panther II 60 terminal:




   C. Panther II 96 Terminal

       The required technical data for the proposed Panther II 96 earth station is provided in the

Form 312. This terminal employs a 96 centimeter antenna; and the half-power beamwidth

required in Section 25.130(f) is 0.8 degrees. In addition, for blanket licensing of transmitting


       Earth stations in the 29.5-30.0 GHz band, the Commission adopted off-axis EIRP spectral density

       levels contained in Section 25.138(a). As illustrated in the off-axis EIRP spectral density plots

       in Exhibit B, the proposed terminal type meets the performance requirements in Section 25.138

       (a) under clear sky conditions.

               Below is an image of the Panther II 96 terminal:




III.          RESPONSE TO QUESTION 36

              ISAT US submits this response to Question 36 of the FCC Form 312 out of an abundance

       of caution. In 2005, the Commission dismissed a Petition for Declaratory Ruling (the “Petition”)

       filed by Inmarsat Mobile Networks, Inc.’s affiliate, Inmarsat Global Limited (“Inmarsat

       Global”), seeking United States market access to provide MSS in the 2 GHz band. Subsequent to

       Inmarsat Global’s filing, the Commission assigned all 2 GHz spectrum currently allocated for

       MSS in the United States to two other satellite operators, and thus dismissed Inmarsat Global’s

       Petition.
