摘　　要：基于卫星工具软件(satellite tool kit,STK)强大的建模与仿真、分析与计算等功能,对Matlab与STK的连接接口进行研究。建立Matlab与STK之间的通信模型,将STK与Matlab联合仿真分析应用于Walker星座的设计与优化。通过Matlab命令实现对STK的连接、对象创建与数据提取功能,并进行数据可视化处理。结果表明:轨道倾角的变化对寻访时间的影响较大,而轨道平面数的变化对寻访时间影响较小;创建的Walker星座设计的交互界面,可为航天任务仿真分析提供方便有效的支撑平台。Based on the strong modeling and simulation, analysis and calculation of satellite tool kit（STK）, the connection interface between Matlab and STK is studied. The communication model between Matlab and STK is established. The simulation and analysis of STK and Matlab are applied to Walker constellation design and optimization. Realized connect between Matlab and STK, object creation and data extraction functions, and data visualization processing. The results show that the change of orbit inclination has a great influence on the searching time, but the change of the orbital plane number has little effect on the searching time. The interactive interface of Walker constellation design can provide convenient and effective support platform for space mission simulation and analysis.
