Skybase
From Tardis Wiki, the free Doctor Who reference
A skybase was an orbital command centre used by the Earth Empire. Skybases were modular constructs, used in various forms for over three hundred years. They were linked to the planet below via transmat, and functioned as an orbital docking hub for starships.
