摘要: 为了减少月球探测任务设计阶段的开发成本、提高研究效率,提出利用成熟软件卫星工具包(Satellite tool kit, STK)进行分析、设计及验证的一般途径。首先,讨论基于微分改正的月球探测器轨道设计方法。然后,分析利用STK验证圆锥曲线拼接法设计结果的问题及注意事项。最后,针对STK中月面点、月球车运动设置不灵活等问题,利用外部文件导入方式进行分析、验证;在此基础上,给出月面点光照和测控条件分析方法。仿真结果表明,所提出的方法可以有效实现STK对月球探测任务的分析、设计及验证。

Abstract: In order to reduce the cost and improve the research efficiency of lunar exploration during the mission design phase, an approach using STK software was proposed for mission analysis, design and validation. First, trajectory design of the lunar probe was discussed based on differential correction. Then the problems of validating the design result of patched conic technique were analyzed and considerations were listed when using STK for that purpose. Finally, addressing on the inconveniences in STK when it was used to set the lunar point and the motion of lunar rover vehicle, an external file importing method was employed, and the lighting and station coverage of lunar point was analyzed by this method. The simulation results show that the methods proposed can realize efficiently in the mission analysis, design and validation of the lunar exploration.
