The widely-used attitude algorithms for geomagnetic and inertial measurement unit (MAG-μIMU) are extended Kalman filter and complementary filter, which aim to fuse the outputs of the sensors in MAG-μIMU for attitude determination of the carrier. How to determine whether the carrier is moving or not so as to depress the influences of linear acceleration to attitude determination is the key and however...
Magnetic and inertial measurement units (MIMU) are currently being explored as a promising tool for attitude tracking of a moving object, such as human body parts. The function of attitude calculation is realized by using attitude algorithms. The overall performance of these algorithms is seriously influenced by linear acceleration of the moving object. Therefore, there is a requirement to find solutions...
