航天器轨道机动时机建模与仿真

Modeling and Simulation in Orbit Maneuvering Opportunity of Spacecraft

航天器遂行轨道机动任务,机动时机是影响轨道机动消耗的一个重要参数。合理选取轨道机动时机可以节省航天器的机动时间与燃料消耗。根据航天器初始轨道与目标轨道的关系,给出了航天器轨道机动时机的概念与表示方法,建立了航天器轨道机动时机的模型,并进行了仿真分析,得出了航天器的机动能力对于轨道机动时机的影响关系。

Orbit Maneuvering Opportunity is an important parameter influence orbit maneuvering consumption in spacecraft orbit maneuvering, Selecting orbit maneuvering opportunity reasonably can save spacecraft＇s fuel-time consumption. According to the relative ubiety of spacecraft initial and aim orbit, the conception and expression methods of spacecraft orbit maneuvering opportunity were given and the model of spacecraft orbit maneuvering opportunity was developed and analyzed Influence relation of spacecraft＇s maneuvering ability to maneuvering opportunity and maneuvering time was educed.
