大气阻力摄动对低轨微纳卫星轨道影响建模及仿真OA

The orbital position of micro-nano satellites is crucial for their stability in orbit operation and task execution.The long term influence from atmospheric drag and acceleration perturbations leads to the gradual attenuation of important parameters in satellite orbit.In order to investigate this impact in depth,a reliable atmospheric drag perturbation model is established by analyzing the relationship among the drag acceleration of micro-nano satellites in the atmosphere and the windward area,mass,and atmospheric drag coefficient of the satellite.The classical six orbital elements are used to describe the orbital position of micro-nano satellites,and the fourth order Runge-Kutta method is used to solve the corresponding differential equations.The modeling and simulation analysis of the specific impact of atmospheric drag perturbation on the orbit of low orbit micro-nano satellites provide important reference for researchers to develop effective satellite orbit control strategies.
