Aimed at the problem which Mars can rarefy atmospheric dynamic errors that caused by seasonal variations and diurnal changes during Mars areobraking, the orbital dynamic equation including aerodynamic force was established. Through the research of aerodynamic parameter calculation method applied to rarefied flow, the effect of dynamic errors on aerodynamic force and aerobrake result was analyzed. In consideration of the application in Mars exploration, the characteristics of aerodynamic and orbit during Mars aerobraking were simulated under the condition that the atmospheric dynamic errors exist. To assure the safety of spacecraft and the aerobraking duration, the corridor of aerobraking and the requirement of navigation were proposed. The result can be a reference for the aerobraking implementation of future Chinese Mars exploration.
