摘　　要：为提高地磁场估算精度,根据地球磁场及卫星轨道、地理、星体等坐标系间的转换关系给出了中低轨道卫星外层空间地磁场分布的计算模型,并用网格化和插值法建立了地磁场表。对某卫星的仿真结果表明:该法的计算精度较高,有一定的应用价值。According to the geomagnetic field and the transform relationship among the satellite orbit coordinate, geographic coordinate, satellite coordinate and etc, the calculation model of geomagnetic field in space for MEO ＆ LEO satellite to improve the estimation accuracy of the magnetic field in this paper. The geomagnetic field table was established by gridding and interpolation algorithm. The simulation results of some satellite showed that this method had high accuracy, which was valuable.
