These days, you can read in the news that SpaceX requested FCC for permission to change the orbit of the Starlink satellites already in orbit.
Now... from my understanding, the Starlink satellites fly over all the countries in the world more or less.
How it is that SpaceX just needs an OK from the US government? Aren't there other similar regulating entities across the world that, at least in theory, should be asked for the same permission?
[EDIT] I'm reading more on this topic. Here for instance https://www.geekwire.com/2019/spacex-wants-rearrange-starlink-satellites-faster-broadband-ramp/ you can read that SpaceX didn't ask for a permission to change the orbit but just the "spacing" between the satellites. However I don't get how you can increase the space between two satellites without changing at least temporary the orbit of at least one of the two.
