双基站小卫星网的动力学模型及可视性

The Dynamics Model and the Visibility of Twin-Station-Based Micro-Satellite Networks

从航天器飞行动力学角度出发 ,首先建立了小卫星网中小卫星在地球引力场作用下相对空间站的相对运动微分方程 ,然后研究了双基站小卫星网的可视性、对地覆盖时间 ,比较了双基站与地面基站的覆盖性能 。

Based on spacecraft flight dynamics, the relative motion dynamics differential equations of Micro satellite relative to space station by the effect of earth gravitational field is established in this paper. And the visibility of twin station based micro satellite networks is studied. Also the coverage properties of twin station and ground station is compared. Then a conclusion is drawn that the coverage properties to micro satellite networks of space station is much better than that of ground station. Also an example is presented to show the advantage of the twin station.
