New collaboration to demonstrate how terrestrial 5G-based timing can provide scalable solutions to complement and backup GPS

RESTON, Va.–(BUSINESS WIRE)–NextNav, a leader in resilient Positioning, Navigation, and Timing (PNT) technologies, today announced a strategic partnership with Oscilloquartz, an Adtran company and global leader in time synchronization solutions. The companies will showcase how 5G-powered terrestrial PNT and Oscilloquartz’s proven timing technology could enable a scalable complement and backup to GPS capable of keeping critical systems like data centers, utilities, and emergency services running during outages.

This collaboration is intended to lead to a complementary and backup timing service layer to GPS, leveraging existing 5G infrastructure to distribute accurate, UTC-aligned time both indoors and outdoors. By fusing Oscilloquartz’s best-in-class synchronization equipment with NextNav’s terrestrial 5G PNT solution, the partnership will enable greater resiliency by adding an additional timing source to ensure end users are not dependent on a single timing source.

“This partnership is a foundational step toward realizing a systems-of-systems approach to PNT resiliency that helps address an urgent national security and public safety need,” said Sidd Chenumolu, Chief Business Development Officer. “Together with Oscilloquartz, we’re enabling diverse, standards-based timing sources to ensure continuity and security for critical applications — from emergency services to utilities.”

This joint effort responds to a growing market demand for secure, redundant timing solutions amid real-world threats to GPS. By aligning with the ongoing FCC efforts to identify complementary PNT technologies, NextNav and Oscilloquartz are setting the stage to enable a terrestrial 5G-powered 3D PNT solution that advances both private-sector innovation and supports national security priorities.

“Our expertise in delivering resilient synchronization solutions built on diverse cPNT sources makes this collaboration with NextNav a natural fit,” commented Gil Biran, GM of Oscilloquartz, Adtran. “Together, we’re helping to strengthen national infrastructure with secure, GPS-independent timing that supports continuity even in the face of GNSS disruption.”

The demonstration of integrated terrestrial timing will serve as a proof point for 5G-based timing synchronization and serves as a template for future widescale deployments. It’s a forward-looking example of how the timing industry and NextNav can work together to reduce reliance on a single source of timing from GPS and increase national PNT resilience.
