                   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 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 March 18, 2019, to continue its support
of EOR and in-orbit testing being conducted by the launch provider. 1

       1.      Requested STA Operations

        The EOR TT&C and ranging signals are being transmitted in the standard C-band for
which Lockheed Martin has authority under Call Sign E7541. As to the instant request for STA,
Lockheed Martin seeks herein authority to communicate with HS4 as a point of communication
on two C-band frequencies that fall outside of the currently authorized transmit frequencies for
the earth station.

        The TT&C operations that support the HS4 mission are 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 incorporates by reference the radiation hazard study that was included
with its most recent filings at the FCC. In addition, Lockheed Martin is submitting herewith a
Frequency Coordination and Interference Analysis Report prepared by Comsearch.

 STA for this extended mission was most recently granted under FCC File No. SES-STA-20190129-
00049.

       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 is part of a global network of control and
ranging facilities that is being 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 its Carpentersville, NJ earth station
antenna to provide critical TT&C and ranging services during the EOR mission of the HellasSat
4/SaudiGeoSat 1 satellite, for a term of 30 days, form March 18, 2019.
