Abstract:
A system and a method for determining an attitude of a device undergoing dynamic acceleration is presented. A first attitude measurement is calculated based on a magnetic field measurement received from a magnetometer of the device and a first acceleration measurement received from a first accelerometer of the device. A second attitude measurement is calculated based on the magnetic field measurement received from the magnetometer of the device and a second acceleration measurement received from a second accelerometer of the device. A correction factor is calculated based at least in part on a difference of the first attitude measurement and the second attitude measurement. The correction factor is then applied to the first attitude measurement to produce a corrected attitude measurement for the device.
