WebAs mentioned in Section 3.5, a magnetometer is commonly modeled using the following, in which the measurement vector, m ~, consists of a combination of Earth's magnetic field and magnetic fields created by nearby magnetic disturbances. (1) m ~ = S I − 1 ( m E + m e ( t)) + b H I + m i ( t) aglc cannabis onlineWebTherefore a simple method for a basic calibration may be possible: Find the maximum and minimum value for each axis, and get the 1/2 range and zero point. r k = 1 2 ( max ( m k) − min ( m k)) z k = max ( m k) − r k. Shift and scale each axis measurement. m k ′ = m k − z k r k.
