NextNav tests 3D PNT service leveraging cellular infrastructure

NextNav has successfully tested its positioning and timing solution that combines the company’s assured position, navigation and timing (PNT) TerraPoiNT system with existing LTE and 5G network signals. The test, which took place in San Jose, California, demonstrated how TerraPoiNT signals can be integrated with existing cellular signals to deliver accurate 3D positioning and timing information that is not reliant on GPS and GNSS signals.

Using dedicated terrestrial transmitters and LTE/5G signals, NextNav’s system delivers accurate and reliable 3D positioning and timing information and can augment or complement GPS in places where GPS signals may not be available. Integrating TerraPoiNT with LTE and 5G signals provides a rapid and cost-effective approach to scaling resilient PNT solutions in GPS-denied environments.

“Whether its utilities, banks, data centers, transportation, or emergency services, critical infrastructure today is reliant on GPS for position, navigation and timing services, making it highly vulnerable to GPS as a single point of failure” said Ganesh Pattabiraman, co-founder and CEO of NextNav. “With this integration, we have demonstrated a highly scalable and lower cost alternative — a 3D PNT solution which overcomes the vulnerabilities of GPS with a complementary ground-based resilient PNT layer that extends PNT capabilities in urban and indoor environments.”
