You'll have some time at the start of the data set where the filter is converging, but there's nothing you can do about that. AHRS is a collection of functions and algorithms in pure Python used to estimate the orientation of mobile systems. This python program will run for 120 seconds. An update takes under 2mS on the Pyboard. It can calculate the object orientation accurately in short period of time by 3-axis of accelerometer, 3-axis of gyroscope, and 3-axis of magnetometer.
