Analysis on the inversion influence of crustal geomagnetic field at different satellite orbital altitudes

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.
