摘　　要：为了进行航天器系统仿真技术研究,本文提出了应用虚拟现实技术开发GPS运行轨道仿真系统框架体系:利用Matlab仿真,得到并验证了通过对SP3星历数据处理构建正确三维仿真运行轨道的方法;完成了实时交互的三维可视化仿真系统主要功能的实现;最终取得了良好的仿真效果,有利于GPS用户系统的设计与监控。In order to promote innovation and development of domestic spacecraft system simulation technology, the authors developed GPS simulation system framework using virtual reality technology. With Matlab simulation, the method of constructing correct threeimensional simulation orbit through processing the SP3 ephemeris data was obtained and verified. A real-time interactive threedimensional visual simulation environment was realized. The test result was good and it could be beneficial to GPS designing and monitoring.
