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 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.
Mike Horton is an American engineer and serial deep-tech founder who turns physics into products. He co-founded Crossbow Technology in 1995 out of UC Berkeley, commercialized MEMS motion sensors, and sold the company for about $50 million. He later built GEODNET, a blockchain-incentivized network of roughly 21,000 ground stations that has become the world's largest decentralized GNSS reference network, and now leads HYFIX Spatial Intelligence, a Santa Clara startup that raised a $15M seed led by Craft Ventures to build American-made positioning-and-autonomy chips for drones and robots.
Brian Manning is the co-founder and CEO of Xona Space Systems, a Burlingame, California startup building Pulsar, a commercial alternative to GPS broadcast from a planned 258-satellite constellation in low-Earth orbit. A former SpaceX engineer who worked on the Falcon 9 thrust structure, Manning reunited eight Stanford aerospace graduates over pizza and beer in 2019 to chase a question nobody had answered: why has no one built a private, encrypted, centimeter-accurate navigation network? In 2022 Xona launched Huginn, the first commercial satellite navigation mission in orbit, and in March 2026 closed an oversubscribed $170 million Series C to scale manufacturing and begin deploying production satellites.
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.
