Abstract

Embodiments of the present disclosure are directed to various systems, methods and apparatuses of a motion sensing stack, comprising a plurality of magnetometers. Preferably at least four magnetometers are included and at least one magnetometer is out of the plane of at least three other magnetometers. Preferably, the stack includes an 18D IMU (inertial measurement unit). Preferably, the 18D IMU features a 3D accelerometer, a 3D gyroscope and at least four 3D magnetometers. Alternatively, optionally a 9D IMU is provided, comprising a 3D accelerometer, a 3D gyroscope and one 3D magnetometer. The IMU may optionally be MEMS (microelectromechanical system) based.
