VIAVI Introduces Robust PNT Solution for Critical Infrastructure

SecurePNT and SecureTime, in collaboration with VIAVI, have introduced a groundbreaking solution that enhances assured positioning, navigation, and timing (PNT) systems. This innovative approach incorporates the Fugro AtomiChron® timing service, which facilitates intelligent zero-trust multisource assurance by integrating signals from various GPS and GNSS constellations, including Geosynchronous Orbit (GEO), Low Earth Orbit (LEO), and Medium Earth Orbit (MEO).

Crucial networks worldwide, such as those supporting 5G communications, transportation, energy, public safety, finance, defense, and data centers, heavily rely on publicly available GPS and GNSS signals for synchronization based on timing and location. However, these signals are sometimes unavailable or susceptible to interference through jamming, spoofing, or direct attacks on satellites, posing significant risks with potentially catastrophic outcomes. In response, governments are increasingly mandating that providers of critical infrastructure enhance the resilience of their networks by adopting more secure and responsible PNT services.

VIAVI's established portfolio of assured PNT products has a proven track record of delivering redundant timing and location security across civilian and military applications. By leveraging connectivity to a wide array of timing sources available in the market, VIAVI's SecureTime eGNSSSM GEO service, powered by the Fugro AtomiChron® timing source, offers authenticated and encrypted resilience with enhanced accuracy that was previously unattainable through traditional GNSS technologies.

This comprehensive solution embodies the core principles of VIAVI's assured PNT portfolio, featuring trustedPNT™ sensor fusion technology. This technology excels in fusing, weighing, comparing, authenticating, and verifying numerous timing sources from both space and terrestrial platforms within an intelligent zero-trust multisource framework.

One of the standout features of this offering is the patented µTranscoder™, which allows users to seamlessly upgrade their existing GPS/GNSS clocks to a resilient and multisource PNT clock. By inserting the 6200 device between the legacy GPS/GNSS antenna and receiver, users can quickly enhance the security and reliability of their timing systems without the need for extensive modifications.

Furthermore, this system is fully compliant with evolving government guidelines, requirements, and standards, including the DHS Resilient PNT Conformance Framework, the NIST 8323.1 Cybersecurity Framework for PNT Profile, the CISA Federal PNT Services Acquisition Guidance, and the ongoing IEEE Resilient PNT P1952 Standard. These certifications underscore the commitment of VIAVI and Fugro to meeting the highest security and reliability standards in the industry.

Roel de Vries, Business Developer AtomiChron® at Fugro, emphasized the critical role of time synchronization in safeguarding critical infrastructure, stating, “The Fugro AtomiChron® service enhances timekeeping accuracy to the nanosecond and offers protection against GNSS signal spoofing through our navigation message authentication.” Doug Russell, Senior Vice President of AvComm at VIAVI, highlighted the heightened awareness in both the public and private sectors regarding threats to critical infrastructure, particularly the vulnerabilities associated with positioning, navigation, and timing systems.
