NextNav and Oscilloquartz Successfully Integrate 5G-Based Timing for Critical Infrastructure Applications
RESTON, Va. – NextNav (Nasdaq: NN) and Oscilloquartz, an Adtran company, today announced a major milestone with the successful integration of NextNav 5G-based Positioning, Navigation, and Timing (PNT) technology and an Oscilloquartz GNSS-enabled grandmaster clock. This achievement marks a significant step towards the commercialization of a GPS complement and backup serving the needs of national security, public safety and mission critical enterprise timing applications
Specifically, a NextNav 5G PRS-based timing receiver in combination with an Oscilloquartz grandmaster clock successfully produced a GPS-quality timing output signal in the absence of GPS in both outdoor and indoor environments. Fusion of GPS and 5G PRS with an Oscilloquartz grandmaster clock produced resilient pulse-per-second (PPS) and time-of-day (TOD) synchronization outputs.
“This successful integration shows the real-world potential of fusing NextNav’s terrestrial 5G PNT technology with GPS and Oscilloquartz’s world-class synchronization systems,” said NextNav Co-Founder and CTO, Arun Raghupathy. “The result is a far more resilient solution that we believe will ensure continuity of timing across a wide range of critical use cases—from national security and defense to financial services and telecommunications.”
The Oscilloquartz grandmaster clock uses a Zero Trust Architecture (ZTA) and is designed to accept and fuse multiple timing sources, including GPS and NextNav’s 5G PRS-based timing receiver output. This integration ensures GPS equivalent timing performance even in GPS-denied or degraded environments, enabling resilient operation in both outdoor and indoor scenarios where satellite-based signals are unavailable or compromised.
“Reliable and resilient timing is foundational for critical infrastructure,” said Gil Biran, GM of Oscilloquartz, Adtran. “By combining GPS with NextNav’s 5G-based terrestrial signal, we deliver the redundancy and robustness required for next-generation networks, national security, and critical industries that depend on precise synchronization.”
