SaVi 1.4.4 now has a
Debian/Ubuntu
package
that is a
one-click install. As is the Geomview package that SaVi uses for 3D
animation,
which is listed in the Synaptic package manager and under
apt-get.
A couple of clicks, a geomview -run /usr/share/savi/savi,
and
the satellite constellation systems are yours to control, for far less than it
would cost to build Galileo.
I still haven't produced that TIE fighter and Death Star texturemap, though.
