由于传统的地面仿真系统往往是基于VC++语言开发的，开发过程非常复杂，并且进行卫星模拟在轨状态显示时仅能显示数据，或者通过难度很大的OpenGL、D3D等3D编程技术才能进行3D动画显示，造成开发周期长，开发难度大，并且可修改性与可移植性均很差。文章提出了一种新的基于Matlab虚拟现实3D动画显示模块卫星地面仿真系统，采用Matlab已有的模块搭建仿真系统的数学模型及显示系统，可以大大减小系统开发的难度，并且具有3D显示功能。

The traditional ground simulation system is usually developed with VC++, so the development is accordingly very complex. It can only show the data when performing satellite on-orbit state, or develop 3D display system with OpenGL and D3D technique which are very hard and time consuming. So, the paper gives a new design of the Satellite Ground Simulation System based on Virtue Reality 3D Display Model of Matlab which can make use of the existing model in Matlab to establish the mathematical model and the display system. The system has the 3D display function, the difficulty of the system development is also decreased.
