Operating in degraded visual environments - Story
October 16, 2023Operating an aircraft in a degraded visual environment (DVE) is one of the most challenging and stressful tasks for a military pilot, particularly during landing. There are many causes of DVE conditions, including naturally occurring smoke, fog, smog, clouds, sand, dust, heavy rain, blowing snow, darkness, and flat light. Those conditions can happen in combination, and some of the most challenging DVE is induced by the aircraft itself, creating a brownout or whiteout from dust, sand, or snow. Mitigation solutions for the problem of operating aircraft in a DVE fall into a few broad categories: enhanced vision, synthetic vision, and a combination of the two.

Securing military GPS and PNT systems - Story
December 02, 2022Almost every part of our modern economy depends on the Global Positioning System, or GPS. For example, agriculture, construction, mining, rail transportation, and search and rescue all rely on the accurate position, navigation, and timing (PNT) enabled by GPS. An even broader set of industries – communications networks, banking transactions, financial markets, and power grids – rely on GPS for precise time synchronization, to such an extent that most systems would cease working without it. Alternative navigation (ALTNAV) systems can supplement GPS systems in GPS-denied environments using internal clocks and onboard sensors, and those ALTNAV systems should be protected from cyberattacks as well.

Zero trust for military embedded systems - Story
February 11, 2022A zero-trust security posture assumes every user and device is untrusted, even if it is located within the protected perimeter of the local network. The concepts of such perimeterless security have been around for more than a decade, including the “black core” in the architectural vision of the U.S. Department of Defense (DoD) Global Information Grid. Integrators of embedded systems who must have the highest levels of security for such applications as electronic warfare (EW) warning systems can layer higher-level security – such as advanced analytics – atop the embedded computer’s real-time operating system (RTOS) to complete the zero-trust architecture.
