摘要
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—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.
