预定目标的在轨服务飞行器待机轨道分析

Parking Orbit Analysis of On-Orbit Service Vehicle for Specified Servicing Target

为确定单艘在轨服务飞行器(on-orbit Service Vehicle,OSV)针对预定目标的待机轨道,综合轨道动力学和球面几何学原理,利用经典二体动力学模型、霍曼转移轨道模型以及球面三角几何关系,设置具体实例分析OSV针对低、中、高轨道目标的待机轨道选择方法,得到轨道平面调整的能耗和变轨位置与目标轨道平面参数的变化关系,提出待机轨道参数优化的一般思路。该研究可为OSV实施"一对一"在轨服务的待机轨道选择提供理论依据。

In order to get the parking orbit of single on-orbit service vehicle （OSV） for specified servicing target, the approach for low, medium and high orbit target was analyzed using some real examples, in which the space dynamics and the spherical geometry were combined together, and the classical two-body dynamics, Hochmann transfer model and spherical trigonal relationship were concerned. Then, the variability of the energy cost and orbital changing position of OSV for different target orbit plane was presented, as well as the optimization of the parking orbit. The approach provides good reference for the one to one on orbit service operation.
