Abstract
A method, a filtering module, and a computer-readable medium are configured to filter measurements acquired in a sensor reference system. Filtered measurements of motion sensors and a magnetometer attached to the device may then be used to determine orientation of a device in a non-inertial reference system. The measurements are filtered in a reference system, whose position relative to the sensor system can be calculated, and in which gravity and Earth's magnetic field have substantially constant direction and magnitude during the filtering window.
