Not sure if this is the right board for this.
I'm getting good attitude estimation using an MPU9250 accelerometer/gyroscope/magnetometer unit (yaw within 4 degrees, roll and pitch within 2 degrees).
I want to use the accelerometers to aid GPS positioning. I'm correcting for gravity and the accelerometers are well calibrated. But the results I'm getting are not good at all. Is it possible to do inertial navigation (as in estimating distance travelled) with cheap IMUs? Or am I wasting my time?
