SaVi is a program for the visualization and analysis of satellite
constellations.  It provides for the specification and tracking of an
arbitrary number of earth-orbiting satellites.  Satellite orbit
parameters can be dynamically changed at any time during the orbit
simulation.

<p>

SaVi uses Geomview to display a 3D view of the earth in which each
satellite is represented by a small green box.  The Coverage panel
shows a color-coded image of satellite footprints, and tracks their
evolution during the orbit simulation.  The Overhead View panel is
that of an observer looking up from a specific point on the surface of
the Earth. The apparent positions of the satellites are traced across
the observer's sky, which is projected "fisheye" style onto the panel.

motivated by the needs of the community.  For futher information, see
