The 3D High-Precision Electronic Compass is built with an industrial-grade microcontroller, high-accuracy magnetic sensors, and robust driver circuitry to ensure strong reliability and anti-interference performance. It integrates Beiwei Sensing’s advanced hard/soft magnetic calibration algorithms and uses a 3-axis accelerometer for real-time tilt compensation, delivering accurate heading data even in harsh or dynamic environments. With an optimized extended Kalman filter, the compass outputs high-precision 3D attitude information suitable for demanding navigation and positioning tasks. Ideal for satellite tracking, petroleum geological exploration, optical rangefinders, and GPS-assisted navigation.
