Researchers at the University of Rochester in New York have utilized a technique based on the quantum properties of photons to develop the possible first “unjammable” aircraft radar detection system. Traditionally, anti-detection methods include drowning radar signals out with noise or launching false signals. Menhul Malik and his colleagues have developed a system capable of … [Read more...]
Ministry of Defense Launches Anti-Jamming Military Satellite
The Ministry of Defense and aerospace subsidiary Astrium have launched a military satellite equipped with “anti-jamming” capabilities into orbit.

Renowned Aerospace Accident Investigator Comments on EMI in FAA's Evaluation of PED Use on Aircraft
In an effort to reevaluate the use of portable electronic devices (PEDs) during flight, the Federal Aviation Administration (FAA) has requested comments from aircraft operators, pilots, PED manufacturers and PED designers on the current regulations in place. Though the FAA notes in their request that some devices do not transmit or receive any signals, they may still generate … [Read more...]
FAA to Examine the Development of New Spectrum Interference Standards
The Federal Aviation Administration (FAA) is making plans to ask its top advisors on signal interference to assist with mapping out allowable power limits for applications utilizing frequencies close to those used by the satellite navigation community. The decision comes as part of an effort to develop new spectrum interference standards that will maintain the current allocated … [Read more...]
High Power Microwave Missile Disables Computer Systems in Boeing Test
Aerospace company Boeing has successfully completed initial testing on a non-explosive missile that emits high powered microwaves to disable computer and electrical systems.
