Mantle conductivity imaging is one of the scientific goals of the forthcoming Macau ScienceSatellite-1 (MSS-1). To achieve this goal, we develop a data analysis and inversion scheme for satellite magnetic data to probe global one-dimensional (1D) mantle conductivity structures. Using this scheme,we present a new global mantle conductivity model by analyzing over 8 years of Swarm satellite magnetic data. First, after sophisticated data selection procedures and the removal of core and crustal fields, the inducing and induced spherical harmonic coefficients of magnetic potential due to the magnetospheric ring current are derived. Second, satellite
