Backup methods of position, navigation, and timing (PNT) are essential for warfighters operating within GPS-denied environments. Warfighters rely on the U.S. NAVSTAR global positioning system (GPS) and global navigation satellite system (GNSS) for military operations, but are encountering an intense escalation of jamming and spoofing attacks.

The short life cycles of commercial components create many obsolescence headaches for military electronic-system designers as they try to integrate these high-performance devices into air, ground, and sea platforms that must last for decades, have long system development cycles, and require time-consuming testing procedures. As the military looks to leverage more open architectures and commercial off-the-shelf (COTS) technology, the challenge of managing the obsolescence that comes with COTS will only become more difficult.

Is it possible to automate the cyber defense process with machines that can discover, confirm, and fix software flaws in real-time? The U.S. Defense Advanced Research Projects Agency (DARPA) certainly hopes so and is hosting its Cyber Grand Challenge?s (CGC) final competition in August 2016 in conjunction with DEF CON, home of the longest-running attack/defend Capture the Flag global competition for elite hackers, in Las Vegas, Nevada, to find out.

Many military helicopter avionics upgrades are currently underway to enhance communications and situational awareness, leveraging the Future Airborne Capability Environment (FACE) standard and supporting integration of commercial off-the-shelf (COTS) software and hardware. Meanwhile, avionics designers are also addressing cybersecurity concerns in modern aircraft cockpits.

Gallium nitride (GaN) transmitters, radio frequency (RF) tiles, and solid-state modular 3-D radar are among the latest innovations in next-generation military radar systems to embrace commercial-off-the-shelf (COTS) components to reduce costs. Designers of these systems have also adopted modular design to streamline installation and maintenance.
