摘　　要：北斗卫星导航系统(Beidou navigation satellite sys⁃tem,BDS)星座在太空中的空间部署及运行轨迹不可见,地面星座设计及模拟系统昂贵或不公开,导致星座设计内容只能通过课堂进行理论讲授,无法实习实践,影响了测绘学科教学质量,亟待建设北斗星座设计虚拟仿真实验教学系统。针对此问题,设计了一种BDS星座设计虚拟仿真实验教学系统,并介绍了其设计思路、总体框架、实验原理和建设成效。该系统采用Unity3D前端开发平台,利用C#、JavaS⁃cript、HTML5语言开发,包括星座模拟、地面数据模拟和效果评估3大模块,还原了BDS独具特色的混合星座和BDS地面跟踪站设计,并能对星座及地面站的设计效果进行初步评价,提升了教学效果,同时使学生能够从中体验到BDS设计中蕴含的中国智慧。系统已向社会共享,为学科教育和行业发展提供教学实践支撑。The space deployment and orbits of BDS satellites in space are invisible.In addition,the ground constellation de⁃sign and simulation systems are expensive or undisclosed.As a result,the constellation design content can only be taught theoretically through classrooms and cannot be practiced,which affects the quality of talent training in surveying and mapping disciplines.It is urgent to build BDS constellation design virtual simulation experimental teaching system.The design ideas,overall framework,experimental principles and construction results of BDS system constellation design virtu⁃al simulation experimental teaching system are introduced.The system adopts the Unity3D front-end development plat⁃form,and uses C#,JavaScript,and HTML5 languages to de⁃sign three modules:"constellation design","ground monitor⁃ing station data simulation"and"evaluation of effect".It re⁃stores the unique hybrid constellation and ground monitoring station of the BDS.In addition,this experiment can evaluate the effect of constellation design and ground monitoring sta⁃tion simulation,which improves the teaching effect and en⁃ables students to experience the Chinese wisdom contained in the design of the BDS.The system has been shared with the society to provide teaching practice support for subject educa⁃tion and industry development.
