oneNav Unveils World’s First L5-direct™ ASIC, Delivering More Than an Order of Magnitude Improvement in Jamming Resilience for Positioning and Timing, Leveraging GlobalFoundries’ 22FDX® Process Node

Sunnyvale, CA – May 28, 2025 – oneNav today announced the successful bring-up of the world’s first L5-direct™ GNSS receiver ASIC. This groundbreaking L5 receiver, completely independent of vulnerable L1 signals, was rapidly developed and deployed leveraging the advanced GlobalFoundries (GF) 22nm FDX™ platform, benefiting from its exceptional mixed-signal capabilities and ultra-low power performance for both RF and digital domains.

“Our collaboration with GlobalFoundries has been truly catalytic for oneNav,” said Steve Poizner, oneNav CEO. “Choosing their 22FDX+ platform was a strategic decision that has paid off immensely. The node’s exceptional mixed-signal capabilities were crucial for our L5-direct™ RF front-end, while its ultra-low power characteristics are essential for the demanding power budgets of our target applications. GF has been more than just a foundry; they’ve been a true partner in bringing our innovative vision to life.”

oneNav’s L5-direct utilizes a novel “GPU for GNSS” processor architecture that directly acquires and tracks L5 signals without relying on L1 signals, which are widely susceptible to jamming and spoofing—a critical vulnerability for aviation, defense, and consumer GNSS applications. The new technology offers complete immunity to L1 jamming and 30 times greater resilience against in-band jamming in the L5 band. Furthermore, L5-direct delivers a tenfold improvement in measurement precision, enhanced accuracy in dense urban environments, significantly faster initial location acquisition, and lower power consumption compared to L1-dependent receivers.

L5-direct can be deployed in defense, national security, industrial, and consumer applications giving an order of magnitude improvement in jamming resistance for critical GPS-based positioning and timing applications.

“The need for ultra-low power consumption with high jamming resilience is acute in the rapidly growing unmanned vehicle segment, including drones” said Steve Poizner, oneNav CEO.   

Earlier this year, oneNav partnered with three military agencies to evaluate L5-direct in terrestrial, maritime, and aerial environments while under strong simulated electronic warfare conditions. The successful outcomes of these evaluations confirmed the technology’s complete immunity to L1 signal interference and thirty-fold greater resilience to L5 signal interference.

“GlobalFoundries is proud to partner with innovative companies like oneNav to enable the next generation of technologies,” said Ezra Hall, senior director of aerospace, defense, and critical infrastructure at GlobalFoundries. “The successful bring-up of oneNav’s groundbreaking L5-direct™ GNSS receiver on 22FDX+ showcases the unique advantages of our platform. Its optimized power and performance, combined with superior mixed-signal integration, make it an ideal choice for demanding applications requiring both high precision and low power consumption. We are also excited to work with oneNav to extend their products, initially developed for commercial markets, to Aerospace, Defense, and Critical Infrastructure applications which need the capabilities enabled by oneNav’s innovations.”

The specific features of GF’s 22FDX+ platform that enabled oneNav’s breakthrough include optimized power-performance balance, superior mixed-signal integration, ultra-low power consumption, enhanced RF performance, a comprehensive design ecosystem, and broad application reach across multiple sectors.

The L5-direct technology is now available as licensable IP and can be customized for applications ranging from consumer wearables to UAVs. It can also complement M-code in solutions requiring resilience and low power with fast signal acquisition capabilities.
