NASA Takes Aviation Research to the ‘Max’

NASA and the German Aerospace Center (DLR) are studying what happens with engine performance, emissions, and contrail formation when using different types of fuels in jet engines. The international collaboration uses Germany’s Advanced Technology Research Aircraft (ATRA) A320 aircraft burning alternative biofuels, while NASA’s fully instrumented DC-8 Flying Laboratory trails a safe distance behind, sampling and analyzing gases and particles within the ATRA’s wake.

‘Quantum Radio’ May Aid Communications Indoors, Underground, Underwater

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated that quantum physics might enable communications and mapping in locations where GPS and ordinary cellphones and radios don’t work reliably or even at all, such as indoors, in urban canyons, underwater and underground. The technology may help mariners, soldiers and surveyors, among others.

High-Speed Switched Serial Fabrics Improve System Design

Well into its third decade of widespread deployment, VME adopted the new VXS gigabit serial interface, clearly representing the most significant leap in backplane data transfer rates throughout its entire history. Because VXS delivered such a dramatic improvement in embedded system performance, the use of gigabit serial technology was extended to create VPX. The OpenVPX initiative followed shortly thereafter, as risk-averse government agencies mandated the need for industry-wide standards. The hallmark of any successful standard is that it continues to evolve with technology, and none offers a better example than VME’s evolution to VXS and VPX.

High-Speed Real Time Recording Systems

In today’s world of high-speed A/D converters operating in the gigahertz range, real-time signal recording has become a challenging task that requires specialized hardware and intelligent application software. When designing a real-time recorder capable of streaming sustained data to disk at rates of up to 5 GB/sec and higher, the system developer has to consider the limitations presented by the recorder’s operating and file systems, the limitations of disk drive technology, the hardware interfaces, and the RAID controller technology.

Putting FPGAs to Work in Software Radio Systems

FPGAs have become an increasingly important resource for software radio systems. Programmable logic technology now offers significant advantages for implementing software radio functions such as DDCs (Digital Downconverters). Over the past few years, the functions associated with DDCs have seen a shift from being delivered in ASICs (Application-Specific ICs) to operating as IP (Intellectual Property) in FPGAs.
