Abstract :
A newly developed high accuracy, low cost magnetic orientation system is introduced in this paper. The constitution of the orientation system is presented. We get the data of geomagnetic field by the GMR sensor. Because of the complex noise mixing in the signal, we need to decrease the noise so that we can pick up purer geomagnetic signal and realize exact orientation. In the end, we briefly describe the application and the prospect of magnetic orientation system.
