Then , the chaser ' s two orbit roots are selected as variable and visualizing the simulation by contour plot . this part of research draws the conclusion the same as the first part when the target ' s orbit is circular orbit , while the selected two variable can be wildly changed if the target ' s orbit is elliptical orbit . next , wait time before orbit maneuver is simulated 其次,利用可视化的等值线图研究了追踪器轨道两个参数为变量的情况下大范围轨道机动问题,分析表明对圆轨道目标器交会机动时,追踪器轨道根数不宜与目标器轨道根数相差过大,而对椭圆轨道目标器交会机动时,追踪器轨道根数可选范围较大,机动策略和方法富于弹性。
