My SaVi releases include the constellation simulation scripts I've written, as well as enhanced resizeable coverage and fisheye displays.
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 primitive idea of what Geomview can offer.
SourceForge introduces SaVi in an interview. SaVi's features are described in the SaVi user manual. Satellite constellations are introduced in a tutorial using SaVi.
Latest development code with bugfixes is available. Now builds on Tcl/Tk 8.6b1.
The SaVi 1.4.3 release (6 December 2009) adds fisheye option to plot location on coverage map, improves Geomview snapshot handling of file paths containing a space, only uses -redrawn-menus on Mac OS X Leopard when required, uses Tcl/Tk 8.5, builds on Ubuntu 9.10 and Fedora 12.0, fixes saving satellites to save all names but not sunlight, tidies up texts for narrow window widths, makes configuration advice script smarter.
SaVi requires Tcl/Tk. Depending on your installation of Tcl/Tk, you may need to install the tcl-devel package (Red Hat, Fedora) or tcl-dev and tk-dev (Debian, Ubuntu, etc.) to obtain header files to compile against.
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 where credit is given.
