So -- for the purposes of locating a base station that's connected to the starlink network -- the starlink network would rely on the base station reporting it's location? Hopefully not... It certainly doesn't need to just trust it when it has direct observation available too. I'm not suggesting that whatever GPSish thing you'd be able to get out of a pure starlink protocol communication would give you super resolution, but it'd certainly be enough to identify "Crimea" vs "Indian Ocean". And as far as base station -> constellation -- putting a GPS receiver in it is of course smart to speed that up, but I'm not sure even that's necessary or just helpful.
