Abstract: 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.
Keywords: twin-station, micro-satellite networks, visibility, coverage properties.
