Defense
Assured timing for contested environments
Modern defense operations depend on precise positioning, navigation and timing (PNT). Tactical communications networks, C5ISR, electronic warfare (EW), radar and sensor systems, military aviation, naval platforms and tactical ground forces all require accurate and trusted time. From planning through execution, these systems must maintain synchronization even when GNSS signals are degraded, jammed, spoofed or unavailable. Contested electromagnetic environments, adversary denial capabilities and operational constraints such as emission control require timing that can operate independently of external signals. Resilient timing infrastructure helps maintain coordination across platforms, sensors and command networks when GNSS cannot be trusted.
Assured timing resilience
Maintain trusted synchronization across mission systems even when GNSS signals are disrupted, jammed or intentionally denied.
Trusted timing keeps communications, sensors and command networks synchronized when GNSS is degraded, jammed, spoofed or unavailable.
GNSS-independent synchronization
Atomic clocks provide stable onboard timing references that sustain navigation, sensor fusion and communications during extended signal outages.
Building resilient PNT architectures
Resilient defense systems require timing infrastructure that can operate independently while integrating with modern PNT frameworks. The coreSync™ Series OSA 3300 optical pumping cesium clocks establish a stable local reference for extended operation during GNSS disruption, with low phase noise and short-term stability supporting demanding radar and distributed sensing applications. The edgeSync™ Series OSA 5412 and edgeSync+™ Series OSA 5422 distribute precise time across platforms and networks, with accessSync™ Series OSA 5401 and OSA 5405 extending synchronization to compact and distributed deployments. Together, these technologies maintain trusted timing across communications, navigation and sensor systems when satellite signals are degraded or unavailable.
Assured timing for mobile operations
The ruggedSync™ Series OSA 5510 supports mobile command center (MCC) operations in GNSS-denied environments with jamming and spoofing detection and mitigation, M-Code, PRS, Iridium PNT (previously Iridium STL), low phase noise and STANAG/Have Quick.
Preparing for contested future battlefields
Future defense operations will rely on greater connectivity across autonomous and unmanned systems, distributed sensors, command networks and joint multi-domain operations. These environments require precise and trusted timing across systems operating with limited or unreliable access to GNSS. Future defense architectures will rely on diverse timing sources, including LEO-based systems such as Iridium PNT and next-generation atomic clocks to reduce dependence on GNSS while maintaining long-term stability. Resilient timing architectures support evolving navigation strategies designed to operate without guaranteed satellite availability. By integrating atomic timing and advanced synchronization technologies across defense infrastructure, armed forces can preserve operational continuity, system coordination and mission effectiveness as threats to PNT continue to evolve.
