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.
For decades, Global Positioning System (GPS) technology has been incorporated into vehicles and munitions to meet DoD requirements for precision guidance and navigation. GPS dependence creates a critical vulnerability for many DoD systems in situations where the GPS signal is degraded or unavailable.
