                   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 functions 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. The HS4 satellite was successfully
launched on February 5, 2019, aboard an Ariane 5 ECA rocket, from Guiana Space Center. The
spacecraft is currently undergoing its EOR milestones.

        The all-electric propulsion system of HS4 requires extended support for the completion
of the mission. Accordingly, Lockheed Martin is requesting herein extension of its current
authority request for an additional thirty (30) days, from April 15, 2019, to continue its support
of EOR and in-orbit testing being conducted by the launch provider.1

       1.      Requested STA Operations

        Overall, the TT&C operations that support the HS4 launch are conducted 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. Lockheed Martin notes that the Comsearch Report
reflects an extended coordination term accounting for the extended operations contemplated by
this extension request and, as necessary, future extension requests, given the lengthy period of
EOR operations.

 STA for this extended mission was most recently granted under FCC File No. SES-STA-20190310-
00313.

       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 these limited operations in support of the HS4 mission
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 is 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 is
being or 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, from April 15, 2019.
