Ensuring readiness of parts for space
High-performance computing in satellites requires the use of advanced, commercial off-the shelf (COTS) technologies in an environment that has previously been the domain of parts produced in rad-hard foundries. The challenges of this environment require careful implementation of both hardware and software techniques to produce space assets with advanced capabilities and the operational reliability required by the warfighter.

Using calibration to reduce the cost of satellite design and test
What is now known as "NewSpace" introduces business challenges that older satellite programs did not encounter. One example is the creation of constellations of low Earth orbit (LEO) satellites - much smaller and lighter (

DARPA's road show to awareness: SDR Hackfest
U.S. Defense Advanced Research Projects Agency (DARPA) representatives have hit the road in a yearlong campaign to raise awareness of what the agency calls the cyber-physical world, a world filled with an untold number of connected devices. DARPA's Software Defined Radio (SDR) Hackfest hopes to propel the rise in demand for and interest in the electromagnetic spectrum as well as raise awareness around spectrum vulnerabilities.

Unmanned ground vehicle pilots drones for "eye in the sky"
By pairing sensors on an unmanned ground vehicle (UGV) with one or more unmanned aerial systems (UASs), Southwest Research Institute (SwRI) researchers in San Antonio, Texas, can create an "eye in the sky" to improve situational awareness in extreme environments.

Secure satellite communications for warfighters on the move
Mobility, beyond-line-of-sight (BLOS) capability, and data security requirements drive military satellite communications development today. Enabling these capabilities will provide warfighters with reliable and consistent communications throughout a mission, whether stationary or mobile.

Cyber intrusion detection system will focus on mid-flight actionable intelligence
Cybersecurity was a hot topic at the Sea-Air-Space, the Navy League’s Global Maritime Exposition. In this Q&A, Raytheon’s Government Cyber Solutions Director William E. Leigher discusses the challenges that the Department of Defense (DoD) faces when implementing cybersecurity measures to platforms and how the military services need to build high-end cybersecurity measures into a war [...]

Lockheed Martin continues fighting cybercrime for DoD
A recently won $347 million contract enables Lockheed Martin to continue overseeing the world's largest accredited digital forensics lab for five more years, as the company continues its role as the prime contractor for the Department of Defense (DoD) Defense Cyber Crime Center (DC3). Operating under the Air Force Office of Special Investigations, DC3's scope encompasses the entire DoD, providing operations, management, and mission support to more than 10 agencies, including the Department of Homeland Security (DHS), National Security Agency (NSA), the Federal Bureau of Investigation (FBI), the Defense Security Service (DSS), and U.S. Cyber Command (USCYBERCOM).

Taking the complexity out of PCI Express configuration to optimize HPEC system design
Performance is all about eliminating bottlenecks to minimize latency and maximize throughput. Today's high-performance embedded computing (HPEC) systems integrate powerful processing subsystems, each of which might be a fully functional processing node needing to share data with other processing nodes. To maximize overall system performance requires the fastest, most efficient processor-to-processor data paths. With VPX, embedded systems moved away from the VMEbus shared parallel bus model.

Hardening flash storage for ultimate data security
Today's flash storage has made it possible to make embedded systems lighter, faster, more energy-efficient, and more compact than ever. With no moving parts, their reliability is unrivaled and they're the perfect storage medium for rugged applications. However, the nature of flash also makes it more difficult to erase data securely than with traditional magnetic storage. Modern wear-leveling algorithms designed to maximize drive life are extremely effective, but also make it difficult to encrypt files individually or ensure data is ever completely erased. All is not lost: Whole-drive encryption enables engineers to provide strong data security, even with modern flash drives. For military applications its benefits are clear, for both securing data as well as securely erasing sensitive data at the push of a button.

The commonality of COTS solutions for UUVs and UAVs
Some time ago, when designers started thinking about unmanned undersea vehicle (UUV) applications, concerns were raised that the undersea environment might be so different or exotic that standard solutions would need to be significantly modified. To the surprise of many, however, it was found that there is significant commonality between unmanned aerial vehicle (UAV) and UUV environments. There are, to be sure, unique aspects to each type of platform, but in general, standard rugged military commercial off-the-shelf (COTS) embedded solutions are applicable to both.
