                    Description of Operations and Public Interest Statement

         Pursuant to 47 CFR 25.120 of the Commission’s Rules, Lockheed Martin Corporation
(“Lockheed Martin”) hereby requests Special Temporary Authority (“STA”) for a period of
thirty (30) days to operate its Carpentersville, New Jersey fixed earth station (Call Sign E7451)
to provide telemetry, tracking and control (“TT&C”) functions during the post-launch and early
orbit phases (“LEOP”) of operation for the JCSAT-15 satellite.

        JCSAT-15 is destined for in-service operation at 110.0° E.L., and is currently scheduled
for launch on December 20, 2016, aboard an Ariane-5ECA from the European Spaceport in
Kourou, French Guiana.

       Accordingly, Lockheed Martin requests to begin test transmissions on December 17,
2016 in preparation for the launch.1 Further, Lockheed Martin is requesting that the duration of
this STA be a total of thirty (30) days to cover any slippage in the anticipated dates of the various
phases of operation; it nonetheless expects that all Carpentersville operations in support of the
launch will be completed within fourteen (14) days after the JCSAT-15 satellite is launched.

        1.      Requested STA Operations

        Lockheed Martin specifically seeks authority to transmit telecommand signals at the
center frequencies 13750.5 MHz and 13754.5 MHz for in transit telecommand communications
(Earth-to-space), and to receive telemetry signals from the satellite (space-to-Earth) at the center
frequencies 12201.0 MHz and 12203.0 MHz.

        The proposed TT&C operations in support of the JCSAT-15 launch will be on a strictly
non-harmful interference, non-protected basis. Lockheed Martin’s proposed transmissions will
use total input power and emissions for Ku-band telecommand that will fall below the highest
input power, EIRP, EIRP density, and bandwidth prescribed for the telecommand carriers in its
above-referenced FCC license. When no commands are being sent, a CW carrier that is within
the emission of the licensed operation would be present. However, in the case of an anomaly,
extraordinary measures, such as increasing power, may be necessary; if such measures are
required during this STA period, Lockheed Martin will notify the FCC within seven (7) business
days that such measures were needed.

       Lockheed Martin incorporates by reference the radiation hazard study and Schedule B
information that were included with its most recent filings at the FCC.

  The proposed test transmissions would occur over a period of approximately two to three days. During
these tests, the earth station would not be communicating with any satellite; instead, the transmissions
will be made with the antenna at zenith to verify RF functionality.

                                                                                    Attachment
                                                                                     Page 2 of 2




        Lockheed Martin designates Michael Usarzewicz to be the contact person that will be
available whenever transmission to, or reception from, JCSAT-15 is to occur through the subject
earth station. Mr. Usarzewicz can be reached at the following phone numbers:
        (609) 865-2658 (cellular)
        (908) 859-4050 (earth station desk)

       2. Grant of the Requested Authority Will Serve the Public Interest

        Lockheed Martin believes that the limited operations it proposes in support of the launch
of the JCSAT-15 satellite serve the public interest. Lockheed Martin understands that the
JCSAT-15 satellite has been licensed by the Japanese administration for the provision of
communications services to Japanese satellite operator SKY Perfect JSAT. Lockheed Martin’s
Carpentersville earth station will be part of a global network of control facilities that will be used
solely to position the satellite as it progresses from transfer orbit to its final location. No end
user service will be provided within the United States at any time. The safe and orderly use of
the entire geostationary orbital resource and protection of the hundreds of satellites licensed by
the U.S. and other countries that operate there depends in no small part on ensuring that the
JCSAT-15 satellite is controlled while over North America en route to its final geostationary
orbital position. In this regard, Lockheed Martin’s earth station thus will serve a vital function.


                                      *    *    *   *    *

       Lockheed Martin requests authority to operate its Carpentersville, NJ earth station
antenna to provide critical TT&C services during the launch and early operations phase of the
JCSAT-15 satellite, for a term of 30 days, commencing December 17, 2016.
