It's varied from as low as 30ms up to almost 80. Latency is just not going to be great with satellites, seeing that we're pushing it out to fricking space.
Just space alone isn’t enough to say the latency will be worse.
so 3.6 milliseconds raw speed-of-light round trip when overhead.
I don't know what it would be like as it reaches the horizon, and how much latency each hop takes.
