多约束交会对接发射窗口的分析和规划

Analysis and Programming of Rendezvous Launch Window with Multi-Constraints

针对交会对接任务对发射窗口的轨道日照角、光学导航测量设备阳光抑制角和轨道共面等多项约束,建立了交会对接发射窗口计算数学模型,给出了交会对接发射窗口计算方法与流程,分析了各种约束对交会对接发射窗口的影响。计算并构建了交会对接任务目标飞行器和追踪飞行器的年度日照发射窗口集合。按照2种任务规划思路分别给出了确定目标飞行器和追踪飞行器年度共面窗口集合的方法,为多约束交会对接年度发射窗口的日窗口和时刻窗口的分析和规划提供了清晰的结果。仿真结果验证了交会对接年度发射窗口集合的正确性和有效性,模型、方法和结果可作为交会对接任务发射窗口分析和规划的依据。

A mathematical model for the rendezvous launch window based on the rendezvous muhi-constraints including orbit sunlight constraint, sunlight incidence constraint for optics navigation measurement devices and coplanar constraint is established in this paper. The method and the scheme of the rendezvous launch window were presented and the effects of every constraint on the rendezvous launch window are analyzed. The sets of annual rendezvous launch windows of both target and chaser under sunlight constraint are constructed. According to two mission programming modes, methods for determining the annual coplanar launch time sets for both target and chaser are also proposed. The day window and the time window of the annual rendezvous launch window sets with multi-constraints are plainly presented for analysis and programming of the rendezvous launch windows. Simulation computations indicate that the set of annual rendezvous launch windows is correct and valid. The model, the method and the result for the rendezvous launch window are benefit to analysis and programming of the rendezvous mission.
