DMC630 high-precision heading reference system adopts industrial grade microcontroller with high reliability and strong anti-interference ability and high-precision magnetic sensor and driver chip. It also integrates the fast calibration algorithm and anti-interference algorithm independently developed by BeiMicro Sensing, so that it can move in space at will and carry out magnetic field calibration to resist short-time magnetic interference. This product uses a three-axis accelerometer and gyroscope to compensate for the tilt angle, making it able to provide accurate heading data even in extremely harsh environments.
This product comes with IAP upgrade function. Subsequent functions and interfaces will be upgraded through IAP after the programme is updated. It can be customized according to customers' requirements, and can be very conveniently and quickly integrated into various products with electronic compass functions.
