GCM370-MI-SJ 3D Electronic Compass Module for Marine Navigation Surveying

The GCM370-MI-SJ 3D compass features low power consumption and excellent measurement resolution, exhibiting balanced performance in noise suppression and temperature drift stability. Utilizing mature hard and soft iron calibration algorithms, and coupled with a high-performance accelerometer for tilt compensation, it provides reliable heading output across the entire 360° tool face range. Even in applications with fixed magnetic interference, it maintains high measurement consistency and accuracy.

This product integrates a triaxial magnetometer and a triaxial accelerometer. Leveraging a robust industrial-grade microcontroller with strong anti-interference capabilities, it calculates heading data in real time and uses the triaxial accelerometer for heading compensation over a wide range of tilt angles, resulting in excellent overall reliability and stability. Its compact structure and low power consumption make it particularly suitable for applications with strict size and energy consumption requirements, such as drilling measurements, and it can be easily integrated into various terminal devices. Currently, this product is widely used in handheld terminals, mobile devices, antenna attitude control, vehicle systems, and system integration.
