Something else: the satellites are shown in a very unrealistic way: much to close to the earths surface.
http://www.kowoma.de/en/gps/orbits.htm shows the GPS altitude, and geosynchronous orbits (such as for Astra) are shown nicely here: http://www.daviddarling.info/encyclo...ary_orbit.html and on wikipedia.

But then again, I'm not sure what kind of realism is desirable/doable.
I also don't know for which satellites (of the top100) altitude data is actually available.
