Polaris RM3100 Overview
The Polaris RM3100 is a professional-grade redundant compass and barometer module designed for demanding UAV platforms. Combining the industry-leading PNI RM3100 magneto-inductive magnetometer with the high-precision Infineon DPS368 barometer, Polaris delivers clean, interference-free sensor data in a compact standalone package. With DroneCAN communication, it integrates seamlessly with ArduPilot and PX4 flight stacks as a secondary or tertiary sensor node — purpose-built for large multirotors, VTOL, fixed-wing UAVs, and mission-critical autonomous systems where sensor redundancy is essential.
