摘　　要：卫星通信系统的高成本、跨地域和复杂性等特征决定了真实实验教学难以高质量开展,通过设计一个适用于通信专业本科实践教学的虚拟仿真教学实验平台能够明显提升实验的可操作性和试错空间。该平台基于Unity 3D和3DMAX设计并实现了对星、点对点通信、网状网通信等实验,搭建了实验室的虚拟场景、卫星通信的地面站和太空卫星画面。利用华为云服务器实现了该平台C/S架构的教学应用,利用VR设备实现可视化教学应用,增强了实验的便捷性,避免了传统卫星实验中高成本、资源受限、并行实验人数少等问题。The high cost,cross regional,and complexity of satellite communication systems make it dif⁃ficult to carry out high⁃quality real experimental teaching.Designing a virtual simulation teaching ex⁃perimental platform suitable for undergraduate practical teaching in communication majors can signifi⁃cantly improve the operability and trial and error space of experiments.This platform is based on Unity 3D and 3DMAX,and designs and implements experiments such as satellite to satellite,point⁃to⁃point communication,and mesh network communication.It builds virtual scenes for the laboratory,ground stations for satellite communication,and satellite images for space.The teaching application of the C/S architecture of the platform is implemented by using Huawei Cloud Servers,and the visualization teach⁃ing application is implemented by using VR devices,so,it can enhance the convenience of experiments and avoid problems such as high cost,limited resources,and fewer parallel experiments in traditional satellite experiments.
