satellite-navigation
(2)oneNav, Inc.
oneNav is a Silicon Valley semiconductor startup building the world's first L5-direct GNSS receiver - a chip architecture that skips the aging GPS L1 band entirely and uses the modern L5 satellite signal to deliver positioning that is more accurate, lower-power, and far harder to jam or spoof. Founded in 2019 by Steve Poizner and Dr. Paul McBurney, the company sells IP cores and ASICs to smartphone, wearable, IoT and defense customers.
Xona Space Systems
Xona Space Systems is a Burlingame, California company building Pulsar, a commercial low-Earth-orbit constellation that delivers positioning, navigation, and timing (PNT) with centimeter-level accuracy, signals far stronger than legacy GPS, and built-in authentication to resist jamming and spoofing. Founded in 2019 by Stanford and SpaceX alumni, Xona aims to deploy roughly 258 satellites that work with existing devices through software updates, offering a resilient alternative and augmentation to government-run satellite navigation systems.
