    • Abstract
  • Two Fortran programs were compiled based on energy balance approach and short arc integral approach respectively.Both ModelENG（energy balance approach） and ModelSAC1（short arc integral approach） were recovered based on 62 days GOCE orbits,while ModelSAC2 was recovered based on 1 a GOCE orbits.The results show that short arc integral approach has a higher precision than energy balance approach.The precision of the ModelSAC2 is higher than EIGEN-champ03s and ModelGRA,recovered based on 90 days GRACE orbits.ModelSAC2 and GOCE-only model GOCONSGCF2TIMR3 have the same precision before 30 degrees.
