RM3100 was previously used in navigation fields such as land and ocean mapping, sonar positioning, and robotics. Now consumer products can also use the same precision RM3100, said Becky Oh, president and CEO of Precision Navigation. The RM3100 geomagnetic sensor measures the geomagnetic field to provide accurate, reliable, and smooth motion tracking. RM3100 is an industrial-grade product that provides accurate and stable azimuth measurement applications. Its measurement accuracy is less than 10nT—less than 0.1% of the Earth's magnetic field—making it ideal for applications requiring precise heading or azimuth measurement. Performance exceeds existing MEMS or Hall effect sensors by more than 20 times. RM3100 is part of the precision navigation geomagnetic sensor family and includes three advanced coil-type magnetic sensors and ASIC driver chips. It has been enhanced in gain, resolution, and power efficiency, and offers SPI and I2C interfaces for flexible integration. Utilizing proprietary technology, the RM3100 delivers 23 times higher resolution and 27 times lower noise compared to traditional Hall-effect magnetic sensors, enabling accurate heading data across diverse applications.
