VIAVI awarded by US Department of Transportation to advance complementary PNT for critical infrastructure

The DOT CPNT Action Plan aims to test systems that augment or replace GPS/GNSS, providing accurate timing services to critical infrastructure.

VIAVI Solutions has received an award from the US Department of Transportation (DoT) under the Complementary Positioning, Navigation, and Timing (CPNT) Action Plan Rapid Phase II. As part of the program, VIAVI will integrate and test its SecureTime altGNSS GEO-L service and SecurePNT 6200 resilient timing solution at the VALOR™ Lab-as-a-Service for Open RAN and the ORCID integration labs, funded by the NTIA Public Wireless Supply Chain Innovation Fund.

Strengthening Resilient Timing and Navigation Ecosystems

With rising incidents of GPS/GNSS jamming and spoofing, the need for a resilient Positioning, Navigation, and Timing (PNT) ecosystem has become critical. VIAVI’s SecureTime GEO-L service and SecurePNT-6260 solution provide GPS-independent GEO-L satellite timing and precision holdover, ensuring uninterrupted operation for critical infrastructure even in denied or degraded environments.

Driving CPNT Deployment Across Critical Infrastructure

The DoT CPNT Action Plan is designed to evaluate technologies that augment or replace GPS/GNSS for secure timing across sectors including data centers, finance, power grids, and cellular networks. Insights generated from the VALOR, ORCID, and field trials will support broader CPNT adoption nationwide.

Industry Leadership in Assured PNT

“Integration and testing at the VALOR and ORCID labs demonstrate our technology’s operational readiness,” said Doug Russell, Senior Vice President, Aerospace and Defense, VIAVI. Additional government-led field tests will evaluate the GEO-L service and user equipment under live-sky jamming and spoofing conditions.
