分析了地球外部空间磁场性质,阐述了基于虚拟压缩恢复原理建立地磁场模型的一种方法一地磁压缩恢复法,利用国际地磁参考场模型IGRF模拟卫星观测数据对其进行了数值试验检验,初步证实了其有效性和可靠性。
The quality of the geomagnetic field outside the Earth is analyzed. An approach based on the fictitious compress-recovery principle for establishing the geomagnetic filed model is introduced, and a simulative test is provided to analyze the accuracy of this method. The preliminary results show that the proposed approach is valid and reliable.
