First off:

the window that comes up is HOW MUCH of the unit you want to build.

1 - One unit will be built
5 - Five unit will be built
10 - Ten unit will be built

and so on until 200.

The same goes for Satelites, Fighters, Troops, and Mines.

You can Launch Satellites by clicking:

Launch Units:

Click the Launch/Recover Units button

(you can see the description of the buttons by putting the mouse pointer over them)

Keep Clicking the type of unit you want to launch from the left side until you get the amount you want on the left side

and vise versa to recover them.

Or you can click Launch Units Remotely and launch everything you have.

Click the Recover Units Remotely to recover all units at once.
