- The basis of dynamics and simulation includes the iterative flyout angle algorithm to the solutions to lambert problem and battin ' s universal conic section state extrapolate method . then spacecraft ' s orbit roots , maneuver impulse and maneuver time are discussed as the following four part : first of all , the chaser ' s one orbit roots is selected as a variable to simulate its influence to the large scale orbital maneuver . the research reveals fact that the orbit roots both of chaser and target should be close to each other to achieve better maneuver and rendezvous " ability , moreover , the best orbit maneuver and rendezvous occurs when both chaser and target ' s initial phase angle are equal
为了研究了交会机动中追踪器和目标器的轨道根数、机动时限和机动能耗等因素对交会机动的影响,仿真和分析分为以下四个部分:首先,研究了追踪器轨道单个参数为变量情况下两航天器大范围交会机动问题,研究表明,追踪器的变化参量与目标器相应的参量在接近的情况下可以获得良好的交会机动特性,而对于两航天器轨道共面的情况下,初始相位角相等时则获得最佳的机动效果。 - 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。
