航天器交会绝对导航向相对导航过渡阶段的分析与设计

对航天器交会寻的段不同的机动模式,考虑相对导航最远联络距离、最晚联络开始时间以及最早轨道圆化机动时间等约束条件,阐述绝对导航向相对导航的过渡阶段(即介于调相段与寻的段之间的漂移段)的设计问题,包括漂移段终点与相对导航联络点位置的确定以及漂移段起点位置偏差分析,建立了漂移段起点标称位置与调相段机动速度偏差的关系式,给出漂移段起点标称位置范围及调整方法。

Design and Analysis of the Transition Phase from Absolute Navigation to Relative Navigation in Spacecraft Rendezvous Mission

Subject to the homing and phasing maneuvers as well as constraints of the maximal link distance of the relative navigation,the limited liaison time of the relative navigation and the maximal delay permitted by the crew schedule.For various homing maneuver modes,the relationship between the velocity error from the phasing maneuver and the dispersion zone of the initial point of the drift phase were established,and the dispersion zone of the nominal position of the initial point of the drift phase were given.
