What is resilient PNT?
Resilient PNT: The bedrock of our digital world
Positioning, navigation and timing (PNT) underpins modern society. Derived from Global Navigation Satellite Systems (GNSS), low-Earth orbit (LEO) satellites and other primary sources, PNT is crucial for aviation, finance, communications, utilities, national defense and many other critical industries. However, GNSS signals are weak and often unencrypted, making them susceptible to jamming (signal blockage) and spoofing (false data injection). As threats from cyberattacks, space weather, and interference grow, resilient PNT architectures have become vital to ensure continuous, trusted services.
Why is resilient PNT essential?
Cyber hardening, anti-jam antennas, encrypted signals and backup timing sources safeguard PNT feeds against evolving jamming, spoofing and interference.
Oscilloquartz’s resilient PNT solutions safeguard networks against jamming, spoofing and evolving cyber threats – ensuring continuous service in any environment.
Compliance-driven PNT standards
Critical directives, such as US Executive Order 13905, IEEE P1952, NIS2, DORA, MiFID II, PCI‑DSS and EUCS, are driving the adoption of hardened PNT systems and resilience investments.
Implementing robust backup strategies
PNT-dependent infrastructure can be protected through a multi-layered defense strategy. Real-time monitoring, anomaly detection and signal analysis help identify threats early. Backup technologies such as atomic cesium clocks, LEO satellite receivers and ground-based PNT alternatives like eLORAN ensure continuity even during extended GNSS outages. The final layer is mitigation – using anti-jamming antennas and specialized software to counter cyberattacks and interference.
Protecting PNT from edge to core
Our aPNT+™ technology suite protects PNT-dependent networks from the edge to the core, enabling fast prevention, response and recovery when primary PNT sources are compromised.
Resilient timing and synchronization for mission-critical applications
Oscilloquartz’s assured PNT (aPNT+™) portfolio delivers industry-leading protection for PNT-dependent infrastructure. Our platform includes coreSync™, edgeSync™ and accessSync™ grandmasters, featuring advanced multi-band, multi-constellation GNSS receiver technology. These devices ensure continuous and accurate synchronization, even in GNSS-denied environments, by integrating multiple backup sources such as optical cesium atomic clocks and Iridium® LEO satellite receivers. Iridium® connectivity allows devices to function as either a backup or a primary timing source, ensuring resilience in environments where GNSS is unavailable. Additionally, our solutions incorporate intelligent threat detection and mitigation capabilities, safeguarding critical operations against jamming, spoofing and other cyber threats. By adhering to the highest resilience standards, including the DHS Resilient PNT Conformance Framework, our aPNT+™ platform guarantees robust and secure synchronization for mission-critical applications.
