Oh I’m sure someone else on here knows the exact details but here’s my thought….There’s 3 levels of orbit that satellites are positioned in… low earth orbit, medium earth orbit and geosynchronous orbit.

LEO ranges from about 180kms to 2000kms above earth

MEO is from about 2,000kms to 36,000kms above earth

And GEO is 36,000+ kms above.

So when satellites are launched will be put into one of the three levels of orbit above us. From there is down to the complex mathematical equations and timing to launch and aim a satellite to not just a specific orbit but a specific location within that orbit. That’s why when you hear of launches being delayed it’s usually not just for an hour or two. There’s so much that goes on where not only weather plays a factor but in the earth’s rotation relative to where these satellites are to be positioned above us.

Some of these satellites will be in a fixed orbit above us and some will be in a geosynchronous orbit. It’s a very complex and complicated system. When companies are talking hundreds of millions or billions of dollars in equipment, every precaution is taken to avoid a satellite getting rear ended by another lol. But accidents can happen tho.

Hope that helps somewhat and curious to see what the others have to chime in with. Always open to learning and exploring.

Cheers
