SaVi 1.5.0b satellite constellation visualization software released

http://savi.sourceforge.net/

SaVi is software for simulation and visualization of satellite orbits,
especially satellite constellations such as Iridium, Globalstar and O3b.

SaVi 1.5.0b (June 2017) includes rounding fixes to the constellation
generation tools in tcl/constellations.tcl to improve accuracy.

SaVi 1.5.0a (December 2016) includes two one-line codefixes to SaVi 1.5.0
to prevent bugs:
- in tcl/constellations.tcl to allow loading of unnamed TLEs (elsets)
without a name error.
- in tcl/coverage_frames.tcl to enable better detection of gifsicle,
if installed.

The SaVi 1.5.0 release (September 2016) allows coverage maps to be saved
directly as GIF image files, enables saving of animated coverage maps
as gifanims by using gifsicle, adds ability to load TLE elsets directly
from web, works to improve building on SGI Irix, handles Tcl's
interp->result being considered deprecated in Tcl 8.5 and strongly
discouraged in 8.6, fixes dynamic coverage compilation error seen in
recent clang, fixes path-setting problems in launch script, includes
instructions for building under Windows 10 Anniversary Edition, removes
legacy numesh.oogl and has texturemapping always on.
