Strange, there aren't even 20 at a time above Germany.
How many uplinks can one satellite handle?

Re: Satellite Tracker – Live Map of Starlink and 30k Satellites
#92To get a better sense of the scale, if you are viewing this app on a 4K display, with the planet measuring about 2,000 pixels across Earth’s diameter is approximately 12,742 km (7,918 miles), so each pixel represents about 6.37 km (3.96 miles). A Starlink satellite is roughly 6 m (20 ft) wide without its solar panels. This means a one-pixel satellite marker is shown at roughly 1,000 times its true size. So even if th…
There's already so many starlinks in some bits of LEO that a single sat breaking up will lead to a runaway chain reaction that breaks up everything in that orbit quicker than the debris will decay out of it:
> The results indicate the current population of intact objects exceeds the unstable threshold at all altitudes between 400 km and 1000 km and the runaway threshold at nearly all altitudes between 520 km and 1000 km.

Problem is this capability is concentrated in the hands of 1. A private company. 2. Of a single country with inconsistent leaders. I’d be less anxious if Europe had this capability instead.
I don't like that either, but nothing's stopping others from following the same path and achieving the same capabilities, other than their own inability or refusal to do what's already been done. It's been over a decade since Falcon 9's first successful landing and we're only recently starting to see similar feats from others.
Except the space in these orbits is finite and a collision at say 520 km requires quick action or the entire fleet in that orbit will eventually be destroyed.

Europe isn't the sort of place that would develop this capability
France has Eutelsat: https://en.wikipedia.org/wiki/Eutelsat >. Germany had SES/Astra: https://en.wikipedia.org/wiki/SES_Astra >. The EU as a whole as the Galileo satnav / GPS project: https://en.wikipedia.org/wiki/Galileo_(satellite_navigation_... >. There are numerous other EU satellite comms providers, though most are aimed at commercial/broadcast services. That's a departure point for satellite-phone or satellite-…
The EU can technically do it but they won’t. Starlink dwarfs all the services you mentioned. The EU doesn’t even believe in air conditioning much less making a robust satellite network

#95could you use it to make an ultra small (focussed) sat dish?
Re: Satellite Tracker – Live Map of Starlink and 30k Satellites
#96Just thinking out loud: given that we know positions of these satellites, is one able to use it for non-gps navigation? Either by using vision - by tracking or by using some electromagnetic specter - listening to satellites...
Not impossible but it's not as easy as dedicated GNSS satellites. The ranging codes in a GNSS signal are what makes it easy to find your distance from the transmitter. Starlink doesn't have that, there are some observables you could use but it's not simple.

As someone who worked and briefly lived in subsaharan Africa, I will say that the advantages are huge. Bandwidth alone isn't even the whole story - latency really matters too, another area where Starlink is super helpful compared to say, trying to get fiber punched in west from the southeastern parts of Africa. I have not yet mentioned the benefits of state actors not being able to cut your fiber at sea where nobody…
Fantastic now you can browse TikTok in the middle of the desert.

I'd add to your list...Or do Khan Academy, learn how to purify water, find out recent grain prices a 10 hour drive away, decide if your baby's rash needs an expensive trip in to town, and so on.

i just clicked on one satellite and followed it as it moved. it crossed a continent in like a minute. Is that accurate? Seems too fast. Moreover, are the satellites all moving around like that, haphazardly?
It's not haphazard, it's a circular orbit. And at those altitudes satellites move at a little over 7km/s.

What a delusional view of reality. Do you think those who live in areas with zero fixed internet infra has the time nor the resources to sit through a few hours of Khan Academy per day, or the means to build a filter capable of purifying water?
