New RF tuners drive the design of multichannel signal analyzers for SIGINT - Story
November 18, 2016
Here's the problem: Your unmanned aerial vehicle (UAV) is flying through densely populated geography when one of its signal intelligence (SIGINT) systems' radio-frequency (RF) channels detects an emitter signal of interest on a specific frequency, indicating a potential target. It's not enough to know there's a potential threat out there somewhere. You need to know the threat's exact location, and you need to know it in near-real-time. The challenge is that to geolocate a particular emitter, the SIGINT system needs to reassign three or four of its other RF channels, so they can - along with the original channel - perform the interferometry, using TDOA [Time Difference of Arrival] localization techniques, that's needed to zero in on the potential target.

Enabling Mounted Assured PNT with one COTS-based box - Story
October 27, 2016
Today's warfighter depends on GPS signals to acquire accurate position, navigation, and timing (PNT) data. There's a potential downside to dependence on traditional GPS, however: In some terrains, such as dense foliage or urban canyons, GPS signals can become degraded. GPS receivers can also come under attack from adversaries through jamming or spoofing. Given how critical GPS capabilities are for military services, next-generation PNT technologies are emerging to address vulnerabilities from emerging threats and field conditions.

3U power supply combines XMC mezzanine slot expansion and 6-port PCIe switch - News
October 06, 2016
WASHINGTON. At the annual Association of the United States Army (AUSA) meeting, Curtiss-Wright?s Defense Solutions division introduced the 3U embedded power supply that also delivers system I/O expansion without increasing slot count. The PSU3-THOR power supply combines dual XMC mezzanine slot expansion and a 6-port PCI Express (PCIe) Gen2 switch into a 3U VPX slot unit.

Certifying COTS avionics hardware to DAL A is common sense - Story
September 29, 2016
Modern avionics systems continue to become more complex for not only military aircraft, but also commercial aircraft adapting the latest digital cockpits. This complexity and demand for increased performance has placed more pressure on industry and the civil safety certification authorities for aviation worldwide to develop processes for certifying commercial-off-the-shelf (COTS) hardware to highest safety certification level ? Design Assurance Level (DAL) A. In this Q&A with Paul Hart, Chief Technology Officer (CTO) for Curtiss-Wright Defense Solutions, he discusses the objections from the civil aviation authorities to this concept as well as the benefits that occur from certifying COTS hardware to DO-254 DAL A, its similarities to certifying software to DO-178C, and how it might apply to unmanned aircraft. Edited excerpts follow.

NSA-approved two-layer encryption approach slashes cost and development time - Story
September 16, 2016
In today's world, it is becoming increasingly important to be able to protect classified data-at-rest with encryption for critical data, such as that captured and stored during airborne intelligence, surveillance, and reconnaissance (ISR) missions. For some programs with limited budgets and schedule, using National Security Agency (NSA)-approved Type 1 encryption, the highest level of data protection, may prove impractical due to the high cost - typically several millions of dollars for a new development - and long process - typically two to three years that it takes to reach full certification. The cost and schedule required to deliver Type 1 encrypted hardware has meant that industry's ability to provide robust data protection has lagged far behind the demand.
