Lockheed Martin Corporation Temporary Fixed Earth Station STA Attachment Page 1 of 3 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 1 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.
