                                             Exhibit E
                                      Response to Question 43
                                       Application Narrative

                 By this application, ViaSat, Inc. (“ViaSat”) seeks a radiofrequency license from
the Commission for the Ka-band telemetry transmitter and command receiver on the ViaSat-1
satellite, as well as for the autotrack and downlink beacons. ViaSat currently is scheduled to
launch in the fall of this year. After in-orbit testing, ViaSat-1 will be located at 115.1° W.L.

                ViaSat-1 houses a Ka-band communications payload that will be operated under
authority of the government of the Isle of Man and, ultimately, the United Kingdom. The
Commission has authorized ViaSat to provide fixed satellite service (“FSS”) to the United States
using this payload. See IBFS File Nos. SAT-LOI-20080107-00006; SAT-AMD-20080623-
00131 (“First LOI Amendment”); SAT-AMD-20090213-00023 (“Second LOI Amendment”).
See also Report No. SAT-00627 (Aug. 24, 2009) (“LOI Grant”).

                 In the First LOI Amendment, ViaSat submitted a Technical Annex containing
detailed information about the ViaSat-1 satellite—covering, among other things, the technical
parameters of the telemetry, tracking, and command (“TT&C”) elements of ViaSat-1 (including
power levels and link budgets), as well as the physical characteristics and operations of the
satellite (including with respect to orbital debris mitigation, safe flight profile, and post-mission
disposal). See IBFS File No. SAT-AMD-20080623-00131, Technical Annex.1 That Technical
Annex also contains the information contemplated by Sections 25.140(b)(2) and 25.138 of the
Commission’s rules, and demonstrates (among other things) that ViaSat-1 would be operated in a
manner consistent with Commission rules and policies regarding two-degree spacing,
interference abatement, spectrum sharing, and full frequency reuse. As evidenced by the LOI
Grant, the Commission has found that Technical Annex, as well as the data contained in the
Schedule S that accompanied the First LOI Amendment, and the beam patterns and characteristics
provided in the Second LOI Amendment, sufficient to satisfy the Commission’s rules and policies.

                 ViaSat hereby incorporates by reference into this application the Technical Annex
contained in the First LOI Amendment.2 The Schedule S associated with this application contains
other salient information, including the requisite beam patterns, characteristics, and
interconnections with respect to TT&C operations,3 and data about the physical characteristics of
1
    That Technical Annex refers to the ViaSat-1 satellite by its former designation (“VIASAT-
    IOM”).
2
    With respect to Section A.15.3 of that Technical Annex, ViaSat notes that XM Radio Inc.
    (“XM Radio”) has since been authorized to operate XM-1, XM-2 and XM-4 at the nominal
    15.25° W.L. location in formation such that their E/W station-keeping volumes are bounded by
    115.15° W.L. and 115.35° W.L. See IBFS File No. SAT-MOD-20101216-00262. The
    operation of ViaSat-1 at 115.1° W.L. with an E/W station-keeping tolerance of ±0.05°
    eliminates the possibility of any station-keeping volume overlap with the XM Radio satellites.
3
    The Schedule S associated with this application incorporates information about the
    characteristics of the ViaSat-1 ground network that is being deployed, as well as data from
    ViaSat’s satellite manufacturer about the actual beam characteristics of ViaSat-1.


the spacecraft.

               Grant of the instant application would be consistent with the market access
already granted with respect to ViaSat-1, and would ensure that oversight and control over the
physical operation of that satellite are fully within the jurisdiction of the United States. In
addition, such grant would facilitate the prompt provision of broadband service to millions of
Americans that currently lack such service—particularly in rural portions of the country.
Accordingly, ViaSat submits that grant of this application would serve the public interest,
convenience, and necessity, and respectfully requests that the Commission grant this application
on an expedited basis.

         A.       Technical Parameters

               The TT&C elements of ViaSat-1 would operate in accordance with the technical
parameters set forth in the following summary table, as further detailed in the Technical Annex
submitted with the First LOI Amendment and incorporated by reference herein, and the Schedule S
associated with this application:

             Parameter            Transfer Orbit and Emergency          On-Station
        Command/Ranging            29,500.5 MHz4 (LHCP/RHCP) 29,500.5 MHz (LHCP/RHCP)
    Frequencies and Polarizations 29,503 MHz (RHCP/LHCP)        29,503 MHz (RHCP/LHCP)
        Uplink Flux Density                 -76 dBW/m2                 -115 dBW/m2
       Uplink Antenna Beam                     Omni            Gateway (i.e., “A-Type”) Spot
         Telemetry/Ranging             19,701 MHz (LHCP)           19,701 MHz (LHCP)
    Frequencies and Polarizations      19,703 MHz (RHCP)           19,703 MHz (RHCP)
      Downlink Antenna Beam                    Omni            Gateway (i.e., “A-Type”) Spot
     Maximum Downlink EIRP                    14 dBW                      25 dBW

The Schedule S associated with this application also contains the parameters of the autotrack and
downlink beacons referenced in Exhibit A.

                Only ViaSat is currently authorized to conduct FSS operations in the United
States in the portions of the Ka band identified above. Moreover, the TT&C elements proposed
here would operate in a manner fully consistent with ViaSat’s use of the same portions of the Ka
band in other spot beams on ViaSat-1 (as authorized in the LOI Grant), and, as such, have been
self-coordinated. Therefore, this request is fully consistent with the procedures set forth by the
Commission in the Space Station Licensing Reform Order regarding processing of GSO-like
services.5

    Specified frequencies are center frequencies, with an assigned bandwidth of 1 MHz.

    and Order, 18 FCC Rcd 10760, at ¶ 113 (2003) (“Space Station Licensing Reform Order”).


                                                2


         B.     Schedule and Milestones (25.114(c)(12))

                ViaSat-1 is subject to milestone requirements, and has posted a performance
bond, in connection with the LOI Grant. Notably, the Commission has concluded that ViaSat
has satisfied the first three milestones (see DA 10-1715), and the final milestone will be satisfied
shortly after grant of the instant application when ViaSat-1 launches and commences operations.
Moreover, this application does not involve the addition of any frequencies to ViaSat-1. The Ka
band frequencies specified here are already included on that spacecraft, and will be utilized (for
non-TT&C purposes) in other spot beams that form part of the communications payload that is
the subject of the LOI Grant. Accordingly, there would be no need for the Commission to
impose additional milestone obligations on ViaSat in connection with its grant of the instant
application, or to require ViaSat to post a duplicative performance bond.6

         C.     ITU Cost Recovery

                ViaSat unconditionally accepts the responsibility to pay any ITU cost recovery
fees associated with the ITU filings that the Commission makes on ViaSat’s behalf in connection
with this application.

         D.     Waiver Pursuant to Section 304 of the Communications Act

               In accordance with Section 304 of the Communications Act of 1934, as amended,
47 U.S.C. § 304, ViaSat hereby waives any claim to the use of any particular frequency or of the
electromagnetic spectrum as against the regulatory power of the United States because of the
previous use of the same, whether by license or otherwise.

         E.     Schedule S Limitations

               In response to section S7 (n) of the Schedule S form, the receive system noise
temperature is 204174 K for beams TCR and TCL (on-station telecommand) and 389045 K for
beams BNR and BNL (autotrack beacon). The Schedule S software does not allow a receive
system noise temperature of greater than approximately 32800 K to be entered into the form.
Because the receive system noise temperatures for receive beams TCR, TCL, BNR, and BNL are
greater than 32800 K, the Schedule S fields for the receive system noise temperatures of these
beams have been left blank.

    See Telesat Canada, Order, 22 FCC Rcd 588 (2007). To the extent necessary, and for these
    reasons, ViaSat requests a waiver of the milestone and performance bond requirements set
    forth in Section 25.164(a) of the Commission’s rules. 47 C.F.R. § 25.164(a).
