Not that straightforward I wouldn't have thought. Trains don't suffer
turbulence or bank at 20 degrees. Keeping a lock on must be an
interesting problem.

I didn't know there was such a thing as satellite WiFi. Are these
geostationary (over the equator), or does the "straightforward servo system"
have to compute the satellite orbit too?
