Modern expeditionary military missions generate and exchange massive amounts of data that are used to produce situational awareness and guide decision-making. Much of the data must travel long distances along backbone communications networks composed of high-capacity links that connect command centers.
Today’s interconnected wireless world has led to congested airwaves, making Radio Frequency (RF) management a hot topic. For warfighters overseas, efficiently managing the congested RF spectrum is critical to ensure effective communications and intelligence gathering.
Precise timing is essential across DoD systems, including communications, navigation, electronic warfare, intelligence systems reconnaissance, and system-of-systems platform coordination, as well as in national infrastructure applications in commerce and banking, telecommunications, and power distribution. Improved clock performance throughout the timing network, particularly at point-of-use, would enable advanced collaborative capabilities and provide greater resilience to disruptions of timing synchronization networks, notably by reducing reliance on satellite-based global navigation satellite system (GNSS) timing signals.
The continued growth in unmanned, sensor, and networked devices is expected to drive the need for larger, more capable and more diverse communications systems. Among other enhancements, these systems must improve jam-resistance and low probability of detection to keep pace with adversaries’ growing electronic sophistication and must adapt to fast-changing operational environments. By contrast, today’s military communications architectures are static and inflexible.
Defense forces rely on electromagnetic dominance for command, control, intelligence, surveillance, reconnaissance and related applications that use the electromagnetic spectrum. Similarly, spectrum use by our adversaries, and extensive unaffiliated commercial uses result in an increasingly congested, space, time and frequency environment. Severe pressure on available spectrum from all spectrum users creates a situation demanding significant adaptivity and flexibility of our communications systems to communicate successfully and achieve mission goals.
