If our station is so massive, and we have no means of propulsion whatsoever, how have we not fallen out of orbit yet? It seems highly improbable that our orbit would have survived after whatever happened to that moon. In any case, I still don't think that having a seperate, floating structure is a good idea. We're an AI, so our structures are our sphere of influence; but we're still bound by connections. Having a free- floating structure like that, only controlled by wireless signals, is just begging to be stolen or sabotaged.
Besides, if we don't have any thrusters, it's better to keep our facilities close by and secure, no?
Depending on the nature of our orbit (probably quite high) and the fact that the moon we're orbiting doesn't appear to have an atmosphere (enemy used laser weaponry, IIRC), orbital decay could be very, very small. Even more so considering our station is so massive. (The larger it is, the more energy you need to disturb the orbit.)
As for not being flung into outer space after the lundar destruction event, as long as the debris stays more or less together, our station would not be disturbed to greatly. Additionally, depending on our orbit, it's quite probable that the planet had a greater gravitational effect on us than the moon.
As for the communications issue, the idea was that we store our drone in said station. Most of the times these would be out and about, allowing us to save more space in the hull for more important facilities. Hacking issues exist just as much for drones wherether they'e stored in our hull as in another station.
Third, we have subspace energy links FTL communicaton doesn't seem unlikely.
Fourth, distributing facilities is a good idea to prevent one hit for taking everything out.
Close and secure yes, but we have limited space within our shell which is better suited to defensive and utility upgrades.
Also our lack of thrusters makes orbital drop weaponry unusable against anything not directly below us, hence the need for smaller platforms capable of altering their own orbital trajectory.
Only true if we're in a geotationary orbit.
Well, I seem to be going against popular opinion here. Fine, I'll stop opposing the orbital platform- but if we really don't have any thrusters, then I insist we get some. Sattelites in real life have them for a reason; as it is, we're sitting ducks if some kind of large object comes our way. Like, say, a bit of shattered moon, or an asteroid.
If thrusters are against popular opinion, too, then I'd just like to advocTe more station repair and greater structural integrity.
We probably have some sorts of thrusters, but don't expect much out of them. I honestly doubt we can massively influence our orbital trajectory.
