[Starlink] Starlink deplyment in Ukraine

[Larry Press]

Ground stations in Turkey, Lithuania, and Poland are reachable from Kyiv. https://circleid.com/posts/20220301-spacex-starlink-service-in-ukraine-is-an-important-government-asset. The one in Turkey is often out of range.

I actually doubt that the ground stations are in Ukraine, that would require
much more significant setup (think about the engineers flown out to installa
ground station to support Tonga) and would be extremely vulnerable to
disruption.

Remember, service was turned on and dishys delivered in < 48 hours.

disrupting the ground stations in adjacent countries is a rather significant
escalation.

We don't know the full reach of a ground station, but I suspect that some of the
limitations that people have been talking about are as much software/regulations
as RF/hardware, and I would not be surprised if such restritions are being
relaxed a bit there.

So far he has not said anything about the use of them, although some people in
Ukraine had said they have them and are prepared to use them when the wired
Internet is disrupted. I would not expect to hear that much about people using
them in remote areas yet. We'll probably hear more about that weeks to months
later.
