the In a test involving a combination of captive-carry and free-flying miniature air launched decoy jammers (MALD-Js), flying within a simulated operational environment, the USAF demonstrated that the system could protect a full strike package of manned aircraft. Built by Raytheon Missile Systems Division (Tucson, AZ), and with a range of approximately 500 nmi, the baseline MALD platform is an airlaunchable, low-cost, modular, flight vehicle that emulates the radar signatures and combat flight profiles of monitor news US and allied aircraft. The MALD-J variant carries a stand-in jamming system intended to reduce or eliminate the need for manned stand-in jamming aircraft. According to Harry Schulte, vice president of Raytheon Missile Systems’ Air Warfare Systems product line, “Completion of this test removes the last major hurdle toward MALD-J completing a functional configuration audit (FCA).” Upon completion of the FCA, the USAF may authorize a Milestone C decision, beginning production by the end of 2011. Raytheon delivered the first eight tactically-configured MALD-Js to the Air Force in September for initial operational test and evaluation (IOT&E). The MALD-J is scheduled to achieve initial operational capability in 2012. In a related development, the USAF Research Laboratory, Munitions Directorate (AFRL/RW) (Eglin AFB FL), has announced its plans to issue a sole-source Technology Investment Agreement to Raytheon for procurement of the MALD platform for its “Anti Jam - Precision Guided Munition Integration and Demonstration (AJ-PGM I&D) program. As part the Joint Capability Technology Demonstration (JCTD) program, AFRL will demonstrate the use of advanced AJ-PGM technologies in a long-range scenario. The 24-month schedule will include an inert drop test 18 months from the start of the effort. The original MALD contract was competitively awarded to Raytheon in 2003, however, the need to use the vehicle for an in-flight Navigation and Control Technology demonstration was not identified at the outset of the program. – J. Haystead The Journal of Electronic Defense | October 2011 MALD-J SUCCESSFULLY DEMONSTRATES MANNED AIRCRAFT PROTECTION CAPABILITY 15 NAVY STUDIES GPS NAVIGATION ALTERNATIVES Recognizing a need for more reliable and robust GPS, as well as methods to quantify threats to GPS performance that may be termed “situational awareness,” and for affordable and reliable alternatives to GPS, the office of Naval Research (ONR) has issued a Broad Agency Announcement (BAA) for white papers and full proposals addressing the mitigation of denial (interference and jamming) of Positioning, Navigation and Timing (PNT) signals. ONR program officials are interested in three specific areas of research. The first research topic is GPS antijam technology, including adaptive polarization nuller designs, cooperative threat geo-location algorithms for multiple-platforms and networked platforms, and new GPS MUE/MGUE with EW situational awareness and electronic support measures (ESM). The second research area is precision time and time-transfer technology, including ONR-developed, tactical-grade atomic clocks to various sensor systems to per- form multi-static remote sensing; the development of a time-scaling/steering approach for the US Naval Observatory (USNO) master clocks; and the development of a time-scaling approach for multiple tactical atomic clocks aboard ships and other platforms. The third area of interest will focus on non-GPS navigation technology, such as a small, portable quantum physics-based gravimeter/accelerometer for underwater navigation, bathymetric underwater navigation by sonar and lidar, and precise navigation in littoral sub-surface
