Based on the Modified short arc method developed by the satellite gravity team of Tongji University (Shen Y, 2013; Chen Q et al., 2015), the 160 degree and order static gravity field model Tongji GRACE01 was solved using the reduced-dynamic orbit, inter-satellite range rate nonconservative force acceleration, and attitude data published by JPL from 2003 to 2007.
