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.
