Advanced Navigation
Advanced Navigation is a Sydney-based deep-technology company building navigation and autonomy systems that let robots, ships, aircraft, submarines and spacecraft know where they are when GPS is jammed, denied or simply unavailable. Founded in 2012 by Xavier Orr and Chris Shaw to commercialise AI-based inertial navigation research, it now designs and manufactures fibre optic gyroscopes, MEMS inertial sensors, underwater acoustic positioning and a miniature autonomous underwater vehicle across defense, space, marine, mining and commercial markets. In March 2026 it raised US$110M in Series C funding to accelerate its expansion into photonics, AI and quantum sensing.
ANELLO Photonics
ANELLO Photonics is a Santa Clara, California semiconductor and navigation company that builds SiPhOG, described as the world's smallest high-precision silicon photonic optical gyroscope. By shrinking fiber-optic-class gyroscope performance onto a chip, ANELLO delivers inertial measurement units (IMUs) and full inertial navigation systems (INS) that keep vehicles, drones, ships and robots positioned accurately when GPS/GNSS signals are jammed, spoofed or simply unavailable - across land, air and sea. Founded in 2018 by silicon-photonics pioneer Dr. Mario Paniccia and MEMS/inertial-sensor veteran Mike Horton, the company serves defense, maritime, aerospace, agriculture, construction, mining and autonomous-vehicle markets.
HYFIX
HYFIX (HYFIX Spatial Intelligence) is a Santa Clara semiconductor startup building an American-made autonomous systems chip that fuses high-precision GNSS positioning, inertial sensing, flight control, encrypted communications and onboard AI into a single system-on-chip. Emerging from the GEODNET decentralized positioning network, HYFIX aims to give U.S. drone and robotics makers a domestic alternative to Chinese-dominated supply chains, with centimeter-accurate location that resists jamming and spoofing.
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.
ACEINNA
ACEINNA is a Massachusetts-based MEMS sensor company building high-performance, low-cost inertial measurement units (IMUs), GNSS/RTK precision-navigation systems, current sensors, and flow sensors. Spun out of MEMSIC in 2017 with a roughly $50M investment, ACEINNA is best known for its open-source OpenIMU platform and for shipping centimeter-accurate positioning solutions for autonomous vehicles and ADAS at a fraction of the price of legacy systems.
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.
Point One Navigation
Point One Navigation builds the precision-location stack behind autonomous vehicles, drones, robots and survey-grade tools. Its Polaris RTK network, Atlas inertial sensors and FusionEngine software fuse GNSS, inertial data and computer vision to deliver centimeter-level positioning across the US, Europe, UK, Australia, New Zealand and South Korea.
