Abstract: Based on the force analysis of a ground physics experiment system, a mathematical model was built. The effects of liquid resistance, propulsion and simulated gravitation on the orbit were qualitatively and quantitatively analyzed. Specifically, according to the perturbation equations of elliptic orbits, a theoretical model for the ground experiments with liquid resistance, propulsion and simulated gravitation was derived. Then, the effects caused by propulsion bias and simulated gravitation bias were qualitatively and quantitatively analyzed. Finally, numerical simulations were used to verify the results obtained by theoretical analysis.
