I make a couple ships per fleet with only one weapon and loads of point defence. They really do slice through sats, even 100 of them. This point defence ship is good for the hordes of missiles the AI has left on its homeworld or fighters, as well.

I've tried to see if sats can be useful late game, I lay sats with shields, sats with armor, weapons sats. But they are very easy to cut down by the average fleet. With the bonuses the TDM modpack races take, even regular weapons just slice through.
