C9000-B is a high-precision 6-axis full attitude electronic compass launched by Micro-Magic Inc Hi-Tech Company. It is a rectangular shape with a width of only 1.9cm and consists of an industrial grade microcontroller with high reliability and strong anti-interference ability, as well as high-precision inclination sensors, magnetic sensors, and driving chips. The independently developed hard and soft magnetic calibration algorithms enable the compass to eliminate the influence of magnetic fields even in environments with magnetic field interference through calibration algorithms; The patented inclination compensation algorithm compensates for the heading of a large range of inclination angles.
