They are not that organized rather they are well tracked. The satellites are more likely to be hit by a debris or a dead satellite rather than an active satellite. You can’t organize that. After an Iridium satellite collided with a dead Soviet satellite in 2009 the US space surveillance network run by the US military improved the tracking uncertainty greatly and the government authorized it to release accurate collision warnings to commercial and foreign actors. Besides that most active satellites in low Earth orbit are equipped with GPS so their position is known even more accurately than the ground radars are able to determine. Most satellites are now required to be equipped with some kind of propulsion so that they can maneuver in case of a predicted collision. Most collisions are predicted 1-3 days in advance.
That 2009 Iridium collision was actually a freak accident. There are way more small debris around an inch in diameter that we are not capable of tracking than dead satellites yet collisions with them are rare. I believe only a few events since 2009 are attributed to collisions with untrackable debris. That’s the reason low budget satellites are still allowed in orbit without propulsion. The probability of collision with debris is very low. They are launched to a fairly low orbit (up to 600 km) from which they naturally fall down to Earth within 10-25 years. The lower the orbit the faster they reenter. The US regulator is now discussing the reduction of the reentry time to 5 years.
