What is assured PNT?
Protecting critical infrastructure
PNT (positioning, navigation, and timing) data from GNSS satellites can be leveraged to accomplish a multitude of tasks. In fact, PNT services are so useful that much of the world’s critical infrastructure – including transport, energy, and financial markets – has come to depend on it. But GNSS signals are weak, which makes the PNT data they carry highly vulnerable to a range of threats. Whether the integrity of GNSS is weakened by atmospheric phenomena or disrupted by malicious cyber-attacks, governments and businesses know they must invest now to protect lives and livelihoods. Assured PNT (aPNT) is the umbrella term for a suite of advanced technologies that combat natural and human-caused disruptions to GNSS, safeguarding the world’s most critical PNT-based infrastructure.
Bolstering PNT security
Governments across the world have issued directives and orders to protect businesses and society from unavailability or compromised quality of PNT services.
Our Oscilloquartz accessSync™, edgeSync™, and coreSync™ grandmasters feature the industry’s most advanced multi-band, multi-constellation GNSS receiver technology to provide fully backed up PNT services.
Defense in depth
Through a combination of technologies, aPNT renders networks more robust and, when necessary, provides timing information from highly accurate alternative sources.
Multiple layers of protection
The Adtran aPNT+™ platform is founded on three building blocks: detection, mitigation, and backup. To detect possible threats, AI-powered applications enable operators to analyze the condition of each antenna and determine GNSS signal quality in real-time. Intelligent centralized control in combination with advanced detection and monitoring means at the receiver site, allowing operators to resolve issues before they impact the network. To mitigate timing errors caused by cyberattacks and atmospheric phenomena, grandmaster devices combine with multi-band GNSS receivers to render critical infrastructure more resilient while also boosting accuracy. But for those times when GNSS does go down, you need adequate holdover capability, and that’s where PTP grandmasters with rubidium or even cesium atomic clocks step in.
Robust and resilient
By leveraging multi-band, multi-constellation GNSS receivers, operators of critical infrastructure can compensate for atmospheric delay variation and resist jamming and spoofing attacks.
The Adtran aPNT+™ product portfolio
Our Oscilloquartz accessSync™, edgeSync™, and coreSync™ grandmasters feature the industry’s most advanced multi-band, multi-constellation GNSS receiver technology to provide fully backed up PNT services. And when combined with one of our cesium clocks, these devices form an even more precise and stable ePRTC solution capable of providing phenomenally accurate holdover. But pairing our proven hardware with our range of aPNT-optimized intelligent software is the best way to ensure uninterrupted PNT services for critical infrastructure. Handing full control and visibility to operators, our AI-empowered management tools Ensemble Controller, Ensemble Sync Director and SatAware™ deliver real-time analytics of the end-to-end timing network via an intuitive, easy to operate GUI for intelligent fail-safe prevention, response and recovery.
