SaVi 1.4.0 released

This new release of SaVi, the satellite constellation visualization software, lets you simulate systems like Iridium, Globalstar and Sirius Radio in 2D and 3D on your desktop.

The SaVi 1.4.0 release includes new features:
- satellite names
- shows sun lighting on coverage.
- vastly improved high-performance coverage texturemap piping to Geomview.
- varying (1-19) levels of coverage shading, useful for viewing high-diversity constellations such as GPS and Galileo
- can save high-resolution renderings and screen snapshots of the Geomview camera, either singly or in sequence for postprocessing to make movies.... read more

SaVi 1.3.2a released

The SaVi 1.3.2a revision (1 November 2006) makes SaVi easier to build on Linux systems, by adjusting the Linux makefile definitions. See the RELEASE-NOTE file.

The SaVi 1.3.1 and 1.3.0 packages have also been revised in this way.

SaVi 1.3.2 released

http://savi.sf.net/

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.... read more

SaVi development with gcc 4.0 and Mac OS X

SaVi satellite constellation visualization
http://savi.sourceforge.net/

Latest SaVi development gets SaVi building cleanly with gcc 4.0, which permits SaVi to run on Intel Mac OS X using Fink. Check out the latest SaVi from cvs, or help yourself to the 6 August interim SaVi snapshot from:

SaVi 1.3.0 released

This new release of SaVi, the satellite constellation visualization software, lets you simulate systems like Iridium, Globalstar and Sirius Radio in 2D and 3D on your desktop. This release includes all work done for a workshop on satellite applications and constellations given as a guest lecturer at the International Space University Summer Session.

The SaVi 1.3.0a release (19 July 2006) adds satellites counts to the fisheye view, builds on FreeBSD with make ARCH="freebsd", builds on Debian with make ARCH="debian", improves error reporting when the user passes invalid command-line parameters, sets coverage in the Ellipso script, fixes an error when the user specifies a coverage map with extension .gz, ask the user what size Coverage panel is desired, allows satellites and coverage to be edited to hidden in the Coverage panel, improves layout of the Fisheye view, adds simulation of the Disaster Monitoring Constellation and Japanese quasi-geostationary systems, properly handles directory names containing spaces, and, at long last, adds a SaVi user manual.

SaVi 1.2.8 released

http://savi.sourceforge.net/

SaVi allows you to simulate the movement of satellite constellations such as Galileo and Globalstar, in two and three dimensions. (3D viewing requires Geomview, also from Sourceforge.)

The SaVi 1.2.8 release makes the fisheye window a Tk canvas, removing the need to compile with X libraries, bringing the fisheye to Cygwin Insight Tcl users, and making the SaVi binary 20% smaller.... read more

SaVi 1.2.7a released

http://savi.sourceforge.net/

SaVi 1.2.7a includes a version-specific configuration script that refers to savi1.2.7/ rather than savi-dev/. There are no other changes.

SaVi 1.2.7 adds a spherical projection option to the coverage panel, allowing you to see the Earth as a sphere without requiring Geomview. Some minor cosmetic bugs in updating Geomview when static elements like axes are turned on or off, and in updating coverage panel colors when the coverage panel is closed and later reopened, are also fixed.

Some minor cosmetic bugs in updating Geomview when static elements like axes are turned on or off, and in updating coverage panel colors when the coverage panel is closed and later reopened, are also fixed.

Previous releases of SaVi have been repackaged today to correct the Makefile_defs. naming problem that resulted from packaging on Cygwin and a WIndows filesystem. SaVi 1.2.7 has had its Makefile naming changed to permanently avoid this problem on all platforms.

SaVi 1.2.6 released

SaVi 1.2.6 does a much improved job of simulating satellite constellations, such as Iridium and Globalstar, in 3D on your desktop.

SaVi 1.2.6 improves the Geomview rendering experience by making Geomview faster and more responsive, particularly when texturemapping. SaVi 1.2.6 makes dynamic texturemapping of coverage a user menu option, uses temporary files correctly for texturemaps, and can optionally be built to use zlib for on-the-fly compression of dynamic texture maps for Geomview. SaVi 1.2.6 adds an option to turn the Earth outline map on and off.... read more

SaVi 1.2.5 released

SaVi 1.2.5 polishes and improves SaVi considerably over previous releases.

The coverage panel is beefed up, with a menubar and playbar making it easier to use, and with the ability to display coverage in an almost infinite variety of colours.

Texturemapping under Geomview has been improved and is now of much visibly higher quality.

The installation process has been made more helpful.

SaVi 1.2.4 released

SaVi 1.2.4, released 21 December 2004:
- improves README documentation and reporting on build errors,
- improves piping initialisation and compatibility with 64-bit architectures under Geomview,
- improves opening windows on unusual X displays,
- adds Galileo and Draim tetrahedral simulations.

Enjoy using SaVi. Merry Christmas and happy holidays.

SaVi 1.2.3 released

SaVi 1.2.3 adds support for compiling under gcc 3.3.1 (addressing gcc's complaint about building version.c). It's also the fastest release of SaVi ever, with significant speedups when running under Geomview. Better support for building under Cygwin is included.

SaVi 1.2.2a released

SaVi 1.2.2a is a minor revision to the 1.2.2 package, replacing one Tcl statement that prevented running on pre-Tcl 8.4 systems, and removing unnecessary CVS subdirectories.

Like 1.2.2, 1.2.2a features dynamic texturemapping, improved projections and coverage maps, and a host of other improvements to 1.2.1a.

SaVi 1.2.2 released

http://savi.sourceforge.net/

SaVi allows you to simulate satellite orbits and coverage in two and three dimensions. The 1.2.2 release adds realtime 3D texturemapping, new coverage projections, compatibility with Tcl/Tk 8.4 and Cygwin, better file handling, a Sirius Radio simulation, and a host of other improvements.

SaVi development with Tcl/Tk 8.4.0

The SaVi development tree has been updated so that SaVi supports Tcl/Tk 8.4.0, which was released in September 2002.

A simulation of the Sirius Radio elliptical constellation has also been added.

Work is underway on porting SaVi to cygwin, and we would appreciate advice from anyone familiar with use of Tcl/Tk under cygwin.

We're hoping to release SaVi 1.2.2 in the near future.

SaVi 1.2.1a released

http://savi.sourceforge.net/

SaVi lets you visualise, modify and run satellite orbits
and coverage in two and three dimensions.

SaVi 1.2.1a improves the packaging of the 1.2.1 release -
tightens file permissions, turns off building with
debug enabled.

Otherwise, it's identical to the SaVi 1.2.1 release, which
featured usability improvements and the ability to have
the coverage map widened to fill your screen.

SaVi 1.2.1 released

http://savi.sourceforge.net/

SaVi is Satellite Visualization software, originally
created at the Geometry Center. SaVi lets you create,
modify and run satellite orbits in two and three dimensions,
and examine satellite coverage.

View and manipulate constellations of satellites orbiting
the Earth! Simulations of Iridium, Teledesic, Globalstar,
GPS and others are included.

SaVi 1.2.1 includes bugfixes and usabilty enhancements -
the coverage map can now be stretched to fill your monitor.... read more

SaVi 1.2 released

http://savi.sourceforge.net/

SaVi is the Satellite Visualization software originally from the Geometry Center. SaVi 1.2, a long-awaited update, has finally been released.
View and manipulate constellations of satellites orbiting the Earth!

SaVi works well with the 3D renderer Geomview, also a SourceForge project. SaVi requires Tcl and Tk on a unix system; Geomview is optional, though recommended.

Download the SaVi 1.2 and Geomview 1.8.1 releases! (Developers: start with the SaVi 1.2 release for the
oogl/Earth.ppm.Z
compressed file that is not included in savi-dev/ checkouts.)
