长期在轨运行卫星的轨道维持技术

本文研究近地轨道卫星长期在轨运行的轨道维持问题。轨道维持的任务是将卫星的星下点轨迹保持在设计的参考轨迹附近。近地轨道卫星所受的摄动力包括地球引力摄动、日月摄动、大气阻力摄动和光压摄动等,而影响卫星轨道星下点漂移的主要因素是大气阻力摄动。本文给出了一种新的卫星轨道维持策略,数学仿真表明了其有效性。

Orbit Maintenance for Long Life Satellites

This paper investigates the orbit maintenance of long life satellites.The ground tracks of satellites required for mission should be maintained close to those of reference orbits over the lifetime of satellites.The perturbation forces include Earth gravity,lunisolar perturbations,atmospheric drag,and radiation pressure.Among these perturbations,atmospheric drag is the dominant one which causes drift of the ground track.A new maneuver strategy is developed to meet this orbit maintenance requirement.Computer simulations have shown the effectiveness of the scheme proposed.
