I suspect it's the same system with 'satellite' being used as a
bit of hyperbole
Parabole, surely.
Parabolic orbits are open (ie end up shooting off into deep space),
and so not much use for satellites. Personally, i'd never let such a
technically inaccurate pun pass my ellipse.
Satellite *dishes* are parabolic.
Doh! Of course. I wonder why i immediately started thinking about orbital
mechanics? ...
Well, what *else* would anyone think of when different conic sections
are mentioned in connection with satellites?
Besides, dish antennas are three-dimensional, hence paraboloidal.
Too much Star Trek as a kid, probably.
And since when did anything in Star Trek ever have anything to do with
actual orbital mechanics?
