摘　　要：基于相对运动理论,研究了同轨道面内伴随卫星的轨控时机对相对运动椭圆大小改变效率的影响,并用仿真实例进行了验证,证明在相对椭圆上、下点平行于相对运动方向控制对相对运动椭圆大小的改变效率最高;然后以主航天器伴随卫星释放后的轨道驻留为例,应用这一理论求解了燃料最省的轨控策略。Based on the theory of relative movement, the relationship between the orbit control time and the change efficiency of the relative ellipse of the concomitant satellites in the same orbit plane was studied. The simulation validation showed that the change efficiency reached to the peak when the control direction was parallel to the relative movement at the upper point or lower point in the relative ellipse. Then the orbit control strategy of a concomitant satellite released from the host spacecraft was calculated according to the theory, and the minimum fuel expenditure for orbit maintenance was achieved.
