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 problem of remote dual active rendezvous of spacecraft in coplanar near-Earth orbit is theoretically analyzed.According to the basic principles of orbital dynamics, an analytic solution of the characteristic velocities in various situations is derived for the fuel consumption when the spacecraft changes orbit The time strategy of spacecraft orbit transfer is discussed in order to ensure that the spacecraft operating in different orbits will meet at the same time and in the same space.According to the theoretical analysis above, Characteristic speed and process time are lower than the situation of the main passive rendezvous, the single-star fuel consumption is greatly reduced, the advantages of the rapid change over a wide range of more obvious.
