| Abstract: | Satellite tends to be microminiaturization in the future. It needs to adopt a small, cheap and middle precision autonomous navigation system. According to the measurements of three axis magnetometer in the body frame, the parameters of the orbit can be determined by using of Kalman Filter.The result of simulation shows that orbit determination by dint of three axis magnetometer is of medium precision, which can satisfy some requirments of orbit determination. |

| Keywords: | three axis magnetometer autonomous navigation Kalman Filter geomagnetic field |
