Combating Infrared Threats on the Battlefield

There have been several news headlines lately about offenders pointing commercial lasers at helicopters or police personnel, temporarily blinding and distracting them. An increasing number of “laser assault” incidents have led to tougher penalties with fines and jail time in various countries. The lasers typically used in these attacks operate in the visible light spectrum; therefore, these lasers can be blocked by special absorbing optical dyes contained in special laser defense eyewear.

Enhanced SATCOMs for Unmanned Aerial Systems

Satellites launched with the purpose of relaying communications have been enabling around-the-globe transmissions of information for half a century. And in this current era of hybrid warfare, that means this decades-old hardware needs to be able to manage the command and control of unmanned aircraft.

Optical Interconnect Design Challenges in Space

More and more aerospace applications are incorporating fiber optics technology into their designs due to its many advantages over copper. The thinner fiber solutions provide higher speed over a longer distance, are more reliable, offer higher noise immunity and, in many cases, lower the cost of ownership. Additionally, for the same diameter, fiber can pack more data than copper. Fiber is faster than the category 5 and 6 copper cables, approaching the speed of light (31% lower). For copper, pushing the speed beyond 1G is a challenge, but for fiber 10G is quite common. Copper is limited by distance. Usually, signal degradation with copper will occur after about 90 meters (2.7 km maximum for custom systems), while fiber can achieve more than 1.5 km without a problem and can deliver over 80 km depending on transmission signal quality.

High-Performance Computing for the Next-Generation Combat Vehicle

The development of the Next-Generation Combat Vehicle (NGCV) will require technological advancements in many areas, including lethality, protection, autonomy, human–agent teaming, and electromagnetic capabilities. What ties all of these future capabilities together is the need for vast computational resources to support the artificial intelligence (AI) implicit in bringing these advancements to the battlefield. The operating environment of the NGCV will be such that communications will be severely limited, if available at all; systems will be under constant cyber-attack; and adversarial AI may be actively attempting to deceive all sensors — all occurring under severe size, weight, power, and time-available constraints. These factors, and more, are the motivation for developing a strategy of mobile High-Performance Computing (HPC) for the NGCV.
