基于STK的月球任务设计与仿真

Design and Simulation of Lunar Exploration Mission based on STK

利用拼接圆锥曲线法设计月球探测器轨道,一般将向月飞行轨道分为地心轨道、月心轨道和环月捕获等几个主要轨道段。分析了探测器在月球任务不同轨道段的轨道特点,给出了主要定轨参数。为方便进行目标对准,分析了建立辅助平面以实现月球捕获的方法。最后利用卫星工具包(Satellite Tool Kit,STK)软件对整个飞行过程进行了可视化仿真。对于今后的月球任务和深空探测任务具有应用价值。

According to the patched-conic theory, transfer process of lunar probe consists of earth centered trajectory, lunar centered trajectory and lunar orbit capture. By analyzing the character of these different segments, the primary parameters of the transfer process are confirmed. And an assistant plane was introduced to achieve the lunar orbit capture. At last a visual simulation about the whole flight based on STK was set up. This approach can be used as a reference for further deep space exploration missions.
