While I will always be disappointed that we never got to see what the Neo-Sweden space colony (or even Neo-Sweden on Earth) looked like in G Gundam, we did at least get a very brief look at "The Neo-Sweden base" launching rockets for the Gundams on Earth to reach space in one of the last episodes:
My headcanon is that this base is an extremely expanded version of the real rocket launch facility Esrange, in northern Sweden. Presumably, in the Future Century, it's expanded from a test facility for weather balloons and suborbital rockets into an actual "spaceport".
To get slightly more serious for a moment, it's worth noting that such an expansion would probably be made by exploiting land surrounding the current-day Esrange facility, land belonging to the Sámi people, destroying their traditional reindeer-herding grounds to build launchpads and whatnot. But hey, if Neo-Sweden are fine with turning a 17-year-old orphan girl into a mindless berserker, I wouldn't put it past them to have no problems with screwing over an indigenous population. It's not like current-day Sweden hasn't already done that in numerous ways.
