SaVi simulates satellite orbits and coverage, in two and three dimensions. SaVi lets you explore satellite constellations.

SaVi is described in introductory material and is used in academic papers and publications .

SaVi is easy to install or to download to compile yourself. Then take a look at the optional but useful Geomview , which adds 3D rendering to SaVi, or the satellite plot scripts.

SaVi is supported via the SaVi-users mailing list. Information on SaVi development and code enhancing SaVi is available.
