Sorry but I do not understand the graphs.=C2=A0 The URL sounds great.


I have cc=C2=B4d the author.
=C2=A0
For my part, I can tell that I follow one particular sat chosen
arbitrarily (STARLINK-6064) on a public database since some weeks now
and it keeps at around 360km altitude.=C2=A0=C2=A0 That is much lower than =
500-or-so usual.=C2=A0 Maybe it is that lower altitude that permits a highe= r
performance (lower latencies).

Pretty n= eat!

Getting more correlated results from two or more stations i= n the same cell would help.
