航天器轨道 meaning in English

spacecraft orbit

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。
