Lockheed Martin Corporation Call Sign E7541 Earth Station STA Attachment Page 1 of 3 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. 1 STA for this extended mission was most recently granted under FCC File No. SES-STA-20190310- 00313.

Lockheed Martin Corporation Call Sign E7541 Earth Station STA Attachment Page 2 of 3 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.
