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.
