摘　　要：研究卫星编队构型在J2项摄动和大气阻力摄动作用下的演化进程。从相对运动动力学模型出发,分别加入J2项摄动和大气阻力摄动因素,采用数值积分对所获得的运动方程求解,得到参考星和环绕星在惯性坐标系中的绝对运动规律;将两星的绝对运动规律作差后,利用坐标转换矩阵,将惯性坐标系中两星的相对运动规律转换到Hill坐标系中。由于该方法没有经过任何简化,故研究摄动的影响时不存在误差。最后通过仿真分析,给出了J2项摄动和大气阻力摄动作用下卫星编队构型演化的相关结论,并提出进一步研究的方向。The evolvement process of satellite formation under J2 term and atmosphere drag perturbation is researched. By starting from the dynamical model of relative motion and J2 term and atmosphere drag per- turbation factors added, the gained motion equations are solved by numerical integration and the absolute motion rules of the reference satellite and deputy satellite in the inertial frame are obtained. After the sub- traction of absolute motion rules of the two satellites, the relative motion rules in the inertial frame are con- verted into the Hill frame by the conversion matrix. Due to no simplification made in this method, there is no error in the perturbation effort research. Finally, relative conclusion of satellite formation evolvement un- der J2 term and atmosphere drag perturbation is drawn as well as the future research.
