A NewSolution Algorithm of Magnetic Azimuth

摘要：

Comparing with traditional compasses, the digital compass is smaller, lighter, and more reliable. The key of the algorithm which used in the digital compass is sensor calibration and angle solution algorithm. The content researched in this paper is angle solution algorithm,which is based on the measurement data of three-axis accelerometers and three-axis magnetic sensors, solving the angle between the north direction (rolling axis) of the body frame and the north direction of the navigation frame, which aligned with the directions of magnetic north,east, and the local vertical (down).This kind of algorithm is also called magnetic azimuth solution algorithm. A new algorithm called vector cross product method is presented and compared with traditional attitude angle method for principle and accuracy. Advantages and disadvantages of this method are analyzed.
