swarm orbit

[ice-eggs]

Dear GROOPS TEAM,
I hope you are doing well.
When comparing the kinematic orbit of the Swarm satellite released by IFG with the precise orbit provided by ESA, it is found that the differences between the two remain at the meter-level and exhibit oscillatory behavior, both in the inertial frame and in the Earth-fixed frame. What could be the cause of this phenomenon? Is it due to inconsistencies in the terrestrial reference frames adopted by the two datasets?

maybe first, you could investigate the differences in processing configurations between this two agency
