Each unit delivers ultra-low magnetic noise, high measurement resolution, wide adjustable magnetic range and calibrated orthogonality, with built-in hard iron and soft iron compensation to eliminate environmental magnetic interference. Compact, rugged enclosures support broad operating temperature ranges and strong shock resistance, paired with standard digital communication interfaces for seamless data transmission. The magnetic sensors can operate independently or integrate with gyroscopes and accelerometers for multi-axis attitude fusion, supporting inertial navigation, drone orientation, marine heading detection, industrial positioning and robotics.
