                           EXPEDITED TREATMENT REQUESTED

                    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 two temporary-fixed transmit-only earth station antennas within the
perimeter of its Carpentersville, New Jersey fixed earth station (Call Sign E7541) to provide
supplemental command functionality during the Electric Orbit Raising (“EOR”) period of
operation, ranging, and electric propulsion monitoring for the HellasSat 4/ SaudiGeoSat 1
(“HS4”) satellite, which Lockheed Martin has manufactured.

       HS4 is destined for in-service operation at 39.0 E.L., and is currently scheduled for
launch in mid-January 2019, aboard an Ariane 5 ECA rocket, from Guiana Space Center.

        However, the ensure integrity of the proposed operations, Lockheed Martin requests
authority to begin test communications on December 3, 2018, to initiate calibration of the
temporarily deployed antennas in anticipation of the start of EOR.1

        1.      Requested STA Operations

        Lockheed Martin has submitted under separate application a request for Special
Temporary Authority to transmit EOR TT&C and ranging signals under Call Sign E7541. As to
the instant request for STA, Lockheed Martin seeks herein authority to transmit to HS4 as a point
of communication on four discrete C-band frequencies.

        Overall, the proposed TT&C operations in support of the HS4 launch will be on a strictly
non-harmful interference, non-protected basis. When no commands are being sent, a CW carrier
that is within the emission of the licensed operation would be present. 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 is submitting herewith a Frequency Coordination and Interference
Analysis Report prepared by Comsearch.

         The all-electric propulsion system of HS4 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

  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
                                                            Temporary Fixed Earth Station STA
                                                                                  Attachment
                                                                                   Page 2 of 3




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.

       Lockheed Martin designates Michael Usarzewicz to be the contact person that will be
available whenever transmission to HS4 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 HS4 satellite serve the public interest. Lockheed Martin understands that the HS4 satellite
will provide to provide in-orbit backup, redundancy services for HellasSat 3 and further
expansion over Europe and Southern Africa, through increased Ku-band capacity. Lockheed
Martin’s Carpentersville earth station facility 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 HS4 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 the subject earth station antennas to
provide critical services during the EOR mission of the HellasSat 4/SaudiGeoSat 1 satellite, for a
term of 30 days, commencing December 3, 2018.
