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.
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.
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.
