According to faraday electromagnetism induction law , i.e. when a wire loop incises the magnetic force line of the earth magnetic field , it will bring about the induction electromotive force an attitude measurement system was designed based on the earth magnetic field orientation sensor .

根据法拉第电磁感应定律，即线圈切割地磁场磁力线产生感应电动势的原理，设计一种基于地磁方位传感器的姿态测量系统。
