In the usual, simple case one assumes daily returns are IID and lognormally … WebAnother way to correct for angular drift is to incorporate a magnetometer to measure the Earth's magnetic field. Magnetometers have relatively large errors, but they don't suffer from long-term drift. Correcting the position errors created by the drift components of the accelerometer readings requires an absolute position reference of some sort.
