Lockheed Martin Corporation Call Sign E7541 Earth Station STA Attachment Page 1 of 4 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 Eutelsat 7C (“E7C”) satellite. E7C is destined for in-service operation at 7.0 E.L., and is currently scheduled for launch in late June 2019, aboard an Ariane 5 ECA rocket, from Kourou, French Guiana. Accordingly, Lockheed Martin requests authority to begin communications on June 19, 2019, in preparation for the start of EOR. 1 1. Requested STA Operations The EOR TT&C and ranging signals will be transmitted partly in the standard Ku-band for which Lockheed Martin already has authority under Call Sign E7541. As to the instant request for STA, Lockheed Martin seeks herein authority to communicate with E7C as a point of communication on two extended Ku-band frequencies, which fall outside of the currently authorized Ku-band transmit frequencies for the earth station. In all other respects, operation of the earth station will be consistent with the parameters set forth under the existing permanent authority. In order to demonstrate compliance with FCC Report and Order 96-377 regarding operations in the extended Ku-band, Lockheed Martin submits herewith an analysis that states that the proposed operations pose no risk of interference either to U.S. Navy shipboard radar operations or to NASA TDRSS links. The all-electric propulsion system of E7C 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 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. 1 The proposed test transmissions would occur over a period of approximately two to three days. 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 Call Sign E7541 Earth Station STA Attachment Page 2 of 4 Lockheed Martin designates Michael Usarzewicz to be the contact person that will be available whenever transmission to E7C 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 E7C satellite serve the public interest. Lockheed Martin understands that the E7C satellite will be co-positioned with Eutelsat 7B, nearly doubling capacity over Sub-Saharan Africa to make room for several hundred additional digital channels to support the region’s fast expanding television market. Lockheed Martin’s Carpentersville earth station 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 E7C 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 E7C satellite, for a term of 30 days, commencing June 19, 2019.
