摘要
摘要:利用最新的波茨坦地磁场球谐模型（Potsdam Magnetic Model of the Earth，POMME）进行仿真实验，分别模拟出不同卫星轨道高度下的磁测数据.根据仿真的观测数据反演地壳磁场的高斯球谐系数，对反演结果进行对比和分析，总结出卫星轨道高度对反演结果的影响.针对CHAMP卫星实测数据进行地壳磁场反演，由不同轨道高度磁测数据反演得到的磁场（Magnetic Field，MF）系列模型，验证卫星轨道高度对反演的影响，从而为磁测卫星系统设计论证指标中的卫星轨道高度设计提供一定的参考和指导.

Abstract:The latest Potsdam Magnetic Model of the Earth (POMME) is used to simulate the geomagnetic measurement data at different satellite orbital altitudes. Based on the simulated observation data, the inversion results are compared and analyzed, and the influence of satellite orbital altitude to the inversion results is summarized. Crustal geomagnetic field inversion is carried out from the observed data of CHAMP satellite. Magnetic Field (MF) series models obtained from the inversion of geomagnetic data at different orbital altitudes are used to verify the inversion influence of satellite orbital altitude. The methods and conclusions can provide reference and guidance for the design of satellite orbital altitude in satellite geomagnetic measurement system.
