基于STK/MATLAB联合仿真的北斗三号卫星导航系统教学软件设计及应用

Design and application of BeiDou-3 Navigation Satellite System teaching software based on STK/MATLAB co-simulation

北斗卫星导航系统教学是“卫星导航定位”课程的重要组成,是培养我国北斗新时空应用型人才的关键环节,但其相关原理较为抽象复杂,导致学生难以有效理解。因此,为提升课程教学的直观性、立体性和高效性,该文通过分析北斗系统的教学难点,设计了一款基于STK/MATLAB联合仿真的北斗三号系统教学软件。该软件只需简单调节各类参数,即可自动实现混合星座构型模拟、星间链路演示、卫星跟踪分析和系统性能评估等课程内容的仿真。教学成效表明,采用该教学软件,能够使学生更加直观地理解北斗三号系统的空间结构特性、功能创新特色和定位性能优势,有利于激发学生的学习热情,提高课程教学质量,助力推进教育新型基础设施建设。

BeiDou Navigation Satellite System(BDS)teaching is an important part of the“Satellite navigation and positioning”course and a key link in cultivating China’s BDS new time-space application-oriented talents.However,the relevant principles are relatively abstract and complex,which makes it difficult for students to understand effectively.Therefore,in order to improve the intuitiveness,three-dimensionality,and efficiency of course teaching,this paper designs a BDS-3 teaching software based on STK/MATLAB co-simulation through analyzing the teaching difficulties of BDS.By simply adjusting various parameters,the software can automatically realize simulations such as hybrid constellation configuration simulation,inter-satellite link demonstration,satellite tracking analysis,and system performance evaluation.The teaching results show that the use of this teaching software can enable students to intuitively understand the spatial structure characteristics,functional innovation features,and positioning performance advantages of BDS-3,which is conducive to stimulate students’learning enthusiasm,enhance teaching quality,and promote new educational infrastructure construction.
