| 摘要: |
| 未来卫星的发展趋向于微小型化，采用小型化、廉价和中等精度的自主导航系统是非常必要的。利用三轴磁强计量测得地磁场矢量在仪表坐标系中的分量，并通过卡尔曼滤波器来确定卫星的轨道参数。仿真算例结果表明，三轴磁强计定轨方案具有一定的精度，能满足卫星定轨精度的要求。 |

| 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 |
