IMU Madgwick filter pitch effect on roll and yaw

Using even Madgwick provided raw data, algorithm gives inaccuracies on roll and yaw when only pitch angle applied. This is also valid for our data which is collected with BMX055. We apply only pitch, ...

How to detect orientation with accelerometer when vehicle has variable acceleration?

According to my research, in order to detect angular orientation, AHRSs use gyros and accelerometers. Using a gyro on its own does not work well because of integration drift, and only using an ...

Why do magnetometer values change when I move PCB?

I have an MPU9250 on my PCB and I use an AHRS system with a Madgwick filter to get yaw angle. But for some reason - I can't get normal Euler angles (SO question). But I guess, I understood why. When I ...
