savi 1.4.6-1 (ppc64el binary) in ubuntu trusty

 SaVi allows you to simulate satellite orbits and coverage,
 in two and three dimensions. SaVi is particularly useful for
 simulating satellite constellations such as Iridium and Globalstar.
 .
 SaVi can use Geomview, an optional but useful package,
 for 3D rendering.
