卫星编队飞行动力学仿真及其应用

Dynamics Simulation and Application of Satellites Formation Flying

由若干颗小卫星编队飞行组成一个虚拟卫星,其功能相当或超过一颗大卫星,这将开拓小卫星一个完全崭新的应用领域。文章首先研究轨道动力学,系统地研究编队飞行三种动力学模型,其次进行定位卫星和区域导航系统两个实例数学仿真,分析研究各种数学模型的精度和它们的应用场合。

Several small satellites flying in formation may constitute a virtual satellite with the performance the same as or better than a large satellite, which will open up a new application field for small satellites. The formation flying concepts and their application are firstly outlined, then the orbit dynamics of the virtual satellite is investigated. Three kinds of dynamics models are described, the model accuracies and their applications are analyzed through mathematical simulation. At last, the accuracy and the application of each mathematical model are analyzed.
