摘要
从理论上分析了共面近地圆轨道上的航天器的远程双主动交会的问题.根据轨道动力学基本原理,导出各种情况下特征速度的解析解,为航天器变轨时的燃料消耗分析提供了依据.进一步探讨了航天器轨道转移过程中的时间策略,以保证在不同轨道上运行的航天器在同一时刻、同一空间位置交会.上述理论分析的仿真计算结果表明,双主动交会总特征速度和过程耗时都低于主被动交会情形,单星的燃料消耗大大降低,对大范围快速变轨,优势更加明显.
The issue of long-range cooperative rendezvous between two coplanar spacecrafts on the LEO is theoretically analyzed in this article.According to the basic principle of orbit dynamics,the equations of the characteristic velocity in various situations are derived,and provide the evidence for the analysis of the fuel consumption in the orbit transfer.In addition,the orbit transfer time is further discussed in order to ensure two spacecrafts on different orbits for rendezvous at same time and same space position.It will be shown from simulation results that the characteristic velocity of cooperative rendezvous is lower than that of the single initiative rendezvous.The time of the rendezvous process is also shorter.The either spacecraft consumes less fuel,which is of obvious advantage for the fast long-range orbit transfer.
