本文讨论中低轨移动卫星通信的系统设计问题 ,包括星座设计、覆盖率统计和通信线路计算等问题。运用统一建模语言UML、面向对象可视化编程语言Del phi5 .0、科学计算语言Matlab5 .3、动画制作软件Animator等工具研制了中低轨移动卫星通信系统设计综合软件 ,并以此设计了我国中低轨移动卫星通信系统的星座方案各一套 ,同时完成了星座实时动态演示 ,并能实时对全球、中国、北美、欧洲进行覆盖率动态统计和通信线路计算等。
This article discusses the system design issues for low orbital mobile satellite communications, including constellation design, coverage statistics, and communication line calculations. UML, object-oriented visual programming language Del phi5 .0, scientific computing language Matlab5 .3, animation software Animator and other tools have been used to develop the integrated software of low-orbit satellite communication system design. Based on this, Low-orbit mobile satellite communications system constellation of a set of each, while completing the constellation real-time dynamic demonstration, and real-time coverage of the world, China, North America, Europe, dynamic statistics and calculation of communication lines.
