                    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 E7541)
to provide telemetry, tracking, and control (“TT&C”) functions during the Electric Orbit Raising
(“EOR”) period of operation, ranging, and electric propulsion monitoring for the Eutelsat 7C
(“E7C”) satellite.

       E7C is destined for in-service operation at 7.0 E.L., and is currently scheduled for
launch in late June 2019, aboard an Ariane 5 ECA rocket, from Kourou, French Guiana.
Accordingly, Lockheed Martin requests authority to begin communications on June 19, 2019, in
preparation for the start of EOR. 1

        1.      Requested STA Operations

        The EOR TT&C and ranging signals will be transmitted partly in the standard Ku-band
for which Lockheed Martin already has authority under Call Sign E7541. As to the instant
request for STA, Lockheed Martin seeks herein authority to communicate with E7C as a point of
communication on two extended Ku-band frequencies, which fall outside of the currently
authorized Ku-band transmit frequencies for the earth station. In all other respects, operation of
the earth station will be consistent with the parameters set forth under the existing permanent
authority.

        In order to demonstrate compliance with FCC Report and Order 96-377 regarding
operations in the extended Ku-band, Lockheed Martin submits herewith an analysis that states
that the proposed operations pose no risk of interference either to U.S. Navy shipboard radar
operations or to NASA TDRSS links.

         The all-electric propulsion system of E7C requires extended support for the completion
of the mission. Accordingly, Lockheed Martin is requesting that the duration of this STA be a
total of thirty (30) days. Further, a request for extension of the instant STA request for an
additional one hundred eighty (180) days is being filed concurrently to cover the entire period
required to complete EOR and the in-orbit testing being conducted by the launch provider.

  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.


                                                                    Lockheed Martin Corporation
                                                               Call Sign E7541 Earth Station STA
                                                                                     Attachment
                                                                                      Page 2 of 4




       Lockheed Martin designates Michael Usarzewicz to be the contact person that will be
available whenever transmission to E7C 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 E7C satellite serve the public interest. Lockheed Martin understands that the E7C satellite
will be co-positioned with Eutelsat 7B, nearly doubling capacity over Sub-Saharan Africa to
make room for several hundred additional digital channels to support the region’s fast expanding
television market.

        Lockheed Martin’s Carpentersville earth station will be part of a global network of
control and ranging facilities that will be used solely to position the satellite as it progresses from
transfer orbit to its final location and to calibrate electric propulsion. 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 E7C 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 and ranging services during the EOR mission of the E7C
satellite, for a term of 30 days, commencing June 19, 2019.
