GPS-Iridium anti-jam (AJ) Antenna Systems Navy SBIR FY2012.2 Sol No.: Navy SBIR FY2012.2 Topic No.: N122-115 Topic Title: GPS-Iridium anti-jam (AJ) Antenna Systems Proposal No.: N122-115-0600 Firm: JEM Engineering, LLC 8683 Cherry Lane Laurel, Maryland 20707 Contact: James Lilly Phone: (301) 317-1070 Web Site: http://www.jemengineering.com Abstract: JEM Engineering proposes to research the feasibility of a combined Iridium/GPS anti-jam system within a 4" diameter aperture via a multi-element, multi-function antenna. We will develop a combined system architecture and a new algorithm for attaining anti-jam Iridium performance. We seek to achieve low size, weight, and power for the combined antenna and antenna electronics. Benefits: This project, if successful, will provide anti-Jam GPS and Iridium for UAVs, missiles and other munitions, smaller manned aircraft where a large conventional CRPA is not desirable, boats and submarines. It will also provide GPS and Iridium for civilian applications where RF interference is an issue. Return
