translunar

The time systems and the coordination systems that refered to the design process of translunar-trajectory were introduced. The simplified model based on the double two-body hypotheses was given.

对月球转移轨道设计过程中涉及到的时间系统和坐标系统进行了介绍；给出了双二体假设下的轨道设计模型；综合考虑各种影响因素，建立了地月转移轨道的完整动力学模型。

An improved model for translunar trajectory calculation is proposed, which can merge lunar status information directly into the analytical model. Calculations and comparisons show that calculation accuracy can be improved without obvious change of model complexity.

提出了一种改进的地月转移轨道计算模型，改进模型将月球状态信息直接融入解析模型中，经计算对比证明在模型复杂度没有明显变化的前提下提高了模型计算精度。
