Irrelevant.  Upon launch, the satellite has an elliptical orbit.  It has to
undergo acceleration at the far side of the planet in order to achieve a
circular orbit.  Since that point is not within line of sight of the launch
point, no matter what its altitude, how are you getting energy to it at
that point?
