   (i) Anti-jam capability. Antennas and/or antenna systems with ability to respond to incoming interference by adaptively reducing antenna gain in the direction of the interference.

   (ii) Antennas:

   (A). With aperture (overall dimension of the radiating portions of the antenna) greater than 30 feet; or

   (B). With sidelobes less than or equal to -35dB; or

   (C). Designed, modified, or configured to provide coverage area on the surface of the earth less than 200 nm in diameter, where "coverage area" is defined as that area on the surface of the earth that is illuminated by the main beam width of the antenna (which is the angular distance between half power points of the beam).

   (iii) Designed, modified or configured for intersatellite data relay links that do not involve a ground relay terminal ("cross-links").

    Note: GPS receivers designed or modified for use with military unmanned air vehicle systems with less capability are considered to be specifically designed, modified or configured for military use and therefore covered under this subparagraph.

    Any GPS equipment not meeting this definition is subject to the jurisdiction of the Department of Commerce (DOC). Manufacturers or exporters of equipment under DOC jurisdiction are advised that the U.S. Government does not assure the availability of the GPS P-Code for civil navigation. It is the policy of the Department of Defense (DOD) that GPS receivers using P-Code without clarification as to whether or not those receivers were designed or modified to use Y-Code will be presumed to be Y-Code capable and covered under this subparagraph. The DOD policy further requires that a notice be attached to all P-Code receivers presented for export. The notice must state the following: "ADVISORY NOTICE: This receiver uses the GPS P-Code signal, which by U.S. policy, may be switched off without notice."

   (d) Components, parts, accessories, attachments, and associated equipment (including ground support equipment) specifically designed, modified or configure for the articles in paragraphs (a) through (c) of this category, as well as for any satellites under the export licensing jurisdiction of the Department of Commerce, except as noted below.

Explanatory Note

    This language is not intended to preclude a license application of a complete satellite that is under the jurisdiction of the Department of Commerce from including in that license application any directly associated components, parts, accessories, attachments and associated equipment (including ground support equipment) unless such items are specifically identified for control in paragraph (a) or (b) of this category or any other category of § 121.1 of this subchapter. It is understood that spares, replacement parts, ground support and test equipment, payload adapter/interface hardware, etc. are typically provided as part of a satellite launch campaign; however, such items are only exempt from USML licensing when their intended use is directly related to supporting the Commerce-licensed satellite launch campaign. Once the satellite has been successfully launched, it is understood that such items remaining unlaunched will be returned to the United States.

In addition, detailed design, development, production or manufacturing data for all spacecraft systems and specifically designed or modified components thereof, regardless of which U.S. Government agency has jurisdiction for export of the hardware. (See § 125.4 of this subchapter for exceptions.) This restriction does not include that level of technical data (including marketing data) necessary and reasonable for a purchaser to have assurance that a U.S.-built item intended to operate in space has been designed, manufactured and tested in conformance with specified contract requirements (e.g., operational performance, reliability, lifetime, product quality, or delivery expectations) and data necessary to evaluate in-orbit anomalies and to operate and maintain associated ground equipment.
