In order to convert geomagnetic azimuth information detected from fluxgate compass into digital number for computer to process conveniently
tracking azimuth calculation method is applied to fluxgate compass.The principle of fluxgate compass and the geomagnetic signal are analyzed
and then the basic theory of tracking azimuth calculation method is described.The experimental data are given.The experimental results show that azimuth accuracy of fluxgate compass using tracking azimuth calculation method meets the accuracy requirements of geomagnetic compass.
