No, but I found an interesting kludge...

Yes, its easy and even kind of neat.  If you run
  xearth -showmarkers >mymarkers
once, it will dump its internal database to stdout.  Capture it to a
file and edit it to suit.  From then on invoke xearth with:
  xearth -markerfile mymarkers

Now the cool bit.  Every time xearth redraws, it rereads the marker
file.  That means that with a little cron entry dumping the positions
of the satellites into the marker file from an old tracking program
that shows current sub-satellite position, xearth can plot these moving
objects.  Ooooh... neat.  A kludge!
