That's near orders of magnitude more than reality. The only number that matters is the number of satellites that are in communication line of site. A satellite on the other side of the world doesn't help you.

I wonder how many are in view?

gps is 31 total satellites 12,000 miles up

starlink is 10,000 satellites at ~ 300 miles. (and what orbit?)

EDIT: I found this:

-- starlink:

"In any given place there are 3-4 Starlink satellites visible at a time"

https://news.ycombinator.com/item?id=42445512 :)

in december 2024, there were 4,000 starlink satellites in orbit

so starlink is ~ 8 at all times?

-- GPS:

This 24-slot arrangement ensures users can view at least four satellites from virtually any point on the planet.
