PNI Sensor Corporation
Windsor, CA maker of high-performance geomagnetic sensors, AHRS modules, and AI-based inertial navigation for defense and robotics since 1987.
PNI Sensor Corporation, headquartered at 501 American Way, Windsor, California, is a precision positioning and navigation technology company founded in 1987. With over three decades of expertise, PNI specialises in magneto-inductive geomagnetic sensors, sensor fusion algorithms, attitude and heading reference systems (AHRS), inertial measurement units (IMUs), and Edge AI-powered navigation modules. The company's core mission is delivering accurate position and navigation data in environments where GPS is unavailable, unreliable, or denied.
PNI's flagship magnetic sensor is the RM3100 Magnetometer, recognised as the highest-performance geomagnetic sensor in its class, offering precision magneto-inductive sensing for use in robotics, targeting, surveying, and oceanography. The RM3100-CB variant provides the same capability on a compact board for space-constrained applications.
The AHRS and IMU product line includes the TRAX2 attitude and heading reference system, NaviGuider compact AHRS module, Headway multi-purpose inertial module, and TargetPoint-TCM precision compass and tilt module. For digital compass applications, PNI offers the Prime Pro, SeaTRAX-85deg (designed for marine use with wide tilt compensation), TargetPoint3, and TargetPoint-SX.
PNI's most advanced product is FORT (Field Ops Remote Tracker), a low SWaP-C inertial navigation module incorporating AI and ML algorithms. FORT is GPS-jam and spoof resistant and can locate a dismounted soldier to within 1% accuracy in GPS-denied environments. An advanced variant, A-FORT, is in development to extend tracking to drones, unmanned systems, and ground vehicles globally without GPS. A-FORT won the XTechSearch 7 competition and has received US Army SBIR development funding.
PNI's technology is embedded in products from notable customers including Nintendo, Samsung, iRobot, Sony, STMicroelectronics, General Motors, and Ford, spanning applications in consumer electronics, robotics, automotive, military targeting, anti-submarine systems, satellite operations, oil and gas exploration, and consumer gaming. PNI serves both DoD programs and commercial engineering teams with evaluation kits and direct engineering support.
