On some launches which only deployed satellites, I still hear about
"launch windows".  On a mission that must rendezvous with something
already in orbit, there is an obvious launch window.  There are also
time limits associated with sitting on the pad that I understand, but I
sometimes hear about a "launch window" for launching a satellite that is
going into geo-synchronous orbit.  This doesn't make sense to me, since
it seems that launching it an hour later would only result in it
reaching its orbit an hour later.

Could somebody please enlighten me.

Thank you.
