Abstract
Heading tracking technology is applied in many fields such as helm aiming, Virtual Reality etc. In this paper, one kind of orientation tracking system based upon MEMS accelerometer and magnetometer is designed. MCU can get the input data from the sensors through data bus, and upload the data to PC. The corresponding program is designed with Visual C++ to receive data and draw the 3D location in real time. The PC will adjust the attitude angle through Kalman filter. The experiment result show that the system is on operation well, and can be developed more function based upon it.
