摘要:

卫星组网是满足未来空间通信需求的有效方式,为实现空间卫星组网的可视化,设计了一种卫星组网可视化仿真系统；系统由星座设计分系统、星座覆盖性能分析分系统、数据处理分系统和可视化分系统组成；在组网过程中,首先在星座设计分系统中设置星座的参数,根据轨道参数模型计算出星座中每颗卫星的轨道参数,并将计算结果输出给星座覆盖性能分析分系统,完成对纬度、区域和全球覆盖效果的分析、评估和显示；仿真结果表明:系统能够对卫星组网进行实时计算和显示,计算精度比STK仿真软件提高12%,系统运行稳定,界面良好。

Abstract:

Satellite network is an effective method to meet the demand of future space communication, in order to realize the visualization of satellite network, a satellite network visualization simulation system is design. The system includes constellation design sub-system, constellation coverage performance analysis sub-system, data disposal sub-system and visualization sub-system. In the course of networking, firstly the parameters of constellation are set up in constellation design sub-system, orbit parameters of the satellites in the constellation are calculated according to orbit parameter model, and the calculating results are exported to constellation coverage performance analysis sub-system, which accomplishes the analysis, evaluation and display of coverage effect for latitude, region and the global. The results of simulation demonstrate that the system can real-timely calculate and display satellite network, the calculation precision is 12% higher than STK simulation software, the system runs stably and has a good interface.
