PNI Sensor Information

For more than 30 years, PNI Sensor has been a leader in magnetometry, inertial sensing and positioning algorithms, helping some of the world's most demanding platforms determine their position and heading when GPS is jammed, spoofed or simply unavailable. We design high-precision magnetometers, digital magnetic compasses (DMCs), attitude and heading reference systems (AHRS) and assured positioning and navigation (APNT) modules for reliable operation in GPS-denied environments. Our proprietary magneto-inductive technology measures the Earth's magnetic field for reliable heading and, when combined with sensor fusion, positioning algorithms and magnetic reference data, supports GPS-independent positioning. This technology combines high precision and stability with low power consumption for demanding commercial and defense applications. These capabilities form the foundation of our assured positioning and navigation approach. PNI sensor has shipped nearly 100 million RM3100 magnetometer sensors for consumer, industrial, defense and space applications. PNI grew up in the consumer electronics market, where sensors must be small, accurate, power-efficient, cost-effective, reliable and manufacturable at scale. That experience continues to guide our development for defense and other demanding applications, bringing rapid development cycles, low-SWaP-C engineering, design for manufacturing and production scalability to systems intended for field deployment. Across precision-targeting applications, unmanned systems and navigation solutions for dismounted operators, engineers and program leaders at OEMs, prime contractors and defense agencies turn to PNI for reliable attitude, heading and position data when GPS is unavailable What we do • GPS-denied navigation; inertial and magnetic navigation • Magnetometers and magnetometer arrays • Digital magnetic compasses (DMCs) • Attitude and heading reference systems (AHRS) • Multi-node sensor arrays, sensor fusion and positioning
