SaVi
SaVi is satellite visualization software that lets you create, run, examine, and modify satellite orbits in two and three dimensions. Simulations of Iridium, Globalstar, Galileo, GPS, and other satellite constellations are included. SaVi requires Tcl and Tk on a system with Unix libraries. SaVi works well with the 3D renderer Geomview. Geomview is optional, though recommended for its 3D rendering capabilities.

Recent releases
- 10 Feb 2009 21:53
Changes: This release includes fixes for a couple of rare Tcl/Tk errors, makes -redrawn-menus the default on Mac OS X to work around a bug in using the 10.5 Leopard menubar, adds a View Source... option, and adds more elevation circles to large fisheyes.
- 12 Jan 2009 22:32
Changes: This release fixes editing problems with 1.4.0, and adds a complete help and documentation system that describes and explains the available simulated constellations.
- 20 Jun 2008 08:19
Changes: This release includes new features, such as satellite names, display of sun lighting on coverage, vastly improved high-performance coverage texturemap piping to Geomview, and varying levels (1-19) of coverage shading (useful for viewing high-diversity constellations such as GPS and Galileo). SaVi 1.4.0 is compatible with Tk 8.5, the latest GNU make and gcc, and Mac OS X Leopard/XCode 3.0.
- 21 Sep 2006 00:34
Changes: This version improves spherical projection maps, adds Geomview camera options to view north or south pole, and now appears very polished on Mac OS X or Cygwin.
- 09 Sep 2006 11:28
Changes: This includes all work done for a workshop on satellite applications and constellations given as a guest lecturer at the International Space University Summer Session. Fisheye rendering when "satellite cones" is selected was improved. The code compiles under gcc 4.0 and on Mac OS X with make ARCH=macosx. Geomview version and rendering detection were improved, which is useful for the upcoming Geomview 1.8.2 release. Coverage color keys are hidden when coverage or diversity checkboxes are unchecked.
