My SaVi releases include the constellation simulation scripts I've written, as well as enhanced resizeable coverage and fisheye displays.
SaVi is introduced in a SourceForge interview and a short paper. SaVi's features are described in the SaVi user manual. Satellite constellations are introduced in a tutorial using SaVi.
For real-time 3D animations, SaVi can use Geomview, also originally written at The Geometry Center. These videos, interactive java animations and renderings of constellations will quickly give you a quick idea of what Geomview can offer.
Recent SaVi development code with bugfixes is available.
The SaVi 1.4.6 release (12 May 2013) builds on FreeBSD 8.1, supports Cygwin transitioning from Insight Tcl/Tk 8.4 to conventional unix Tcl/Tk 8.5, has launch script tweaks that could support split-tree approach introduced by Debian package maintainers to decrease their breakage (though they have since returned to a single tree), swaps control/shift key selection in main menu to match usual usage.
SaVi requires Tcl/Tk. If you are compiling SaVi, your installation of Tcl/Tk may require you to install the tcl-devel package (Red Hat, Fedora) or tcl-dev and tk-dev (Debian, Ubuntu, etc.). to get the header files to compile against. Alternatively, you can install SaVi as a binary package on Ubuntu, because a Debian/Ubuntu SaVi package is available.
SaVi is supported via the SaVi users mailing list. There's also a SaVi developers mailing list. SaVi development is stored in the SaVi SourceForge repository.
A service rendering SaVi images on request is available.
Any use of SaVi images should credit
SaVi (http://savi.sf.net/).
There are many examples of use of SaVi where credit is given.
