I was thinking about that.  Was there a reason given why they aren't
used off-planet?  Maybe they are SPEOL only?

 
Also... they had to compensate for the differing potential
energies between receiving and transmission sites, as one
could be "traveling" (term used a bit loosely) a lot faster
and in a different direction, and altitude, etc., than
the other.
 
This would otherwise lead to potentially a hefty chunk of
heat being released at the receiving site.
 
(This was, iirc, a plot device in one of his stories).
 
It's bad enough when talking about locations on the
same planet, but if you're looking at space velocities
and energy wells, etc., it's mind boggling...

I think Niven's "All the Bridges Rusting" firstly
shows an interstellar spaceship which can teleport
itself but it needs a receiver, which is in the
outer solar system - so, less deep in the Sun's
gravity well.  I don't reme,ber if that mattered.
Meanwhile, another spaceship is out there and
in trouble.

There's transfer booths at both ends of the trip, Sol, and Alpha
Centauri. Open ended in both cases, I think, so something not
at rest with the booths can transfer through without a collision.
