卫星星座设计仿真软件综述

卫星星座的发展具有数量规模越来越大、网络功能多种多样、网络构成种类复杂的趋势,对星座设计和仿真提出了更高的要求。因此本文从卫星星座设计过程中,确定星座构型和设计星座网络这2个关键步骤出发,对现行的卫星星座设计软件和网络仿真软件进行了深入介绍和比较。从软件功能、软件特性以及软件对于卫星星座的支持程度这3个角度进行分析和比对。最后得出2套通用性较强的仿真方案:基于Linux平台的ns-3(Network Simulator 3)与SaVi(Satellite Constellation Visualization),有更好的灵活性和开放性,且免费、开源;商用软件OPNET Modeler与STK(Satellite Tool Kit),功能模型库更加强大,图形界面完善,易于快速开发和使用。在目前的软件开发条件下,这2种方案能够较好适应星座的仿真设计需求。

Review on Satellite Constellation Design and Simulation Software

Satellite constellation is developing into vaster number of satellites, multiple network features and complicated composition, which leads to higher requirement on the design and simulation of satellite constellations. Because determining the constellation topology and designing the constellation network are the key steps during constellation design, this article gives an in-depth introduction and comparison on the latest constellation design softwares and network simulation softwares. Software functions, software characteristics and their support on satellite constellation are focused. Finally, two simulation schemes are showed to be suitable. One of them is ns-3(Network Simulator 3) and SaVi(Satellite Constellation Visualization), which are based on Linux with high flexibility and openness. The other one is commercial softwares OPNET Modeler and STK(Satellite Tool Kit). They have poweful functions, complete graphical interface and are easy to employ. Under current sofware development conditions, the two schemes can be better adapted to satellite constellation.
