SaVi is software written to facilitate the visualization and analysis of satellite constellations.
SaVi simulates satellite orbits and coverage, in two and three dimensions. SaVi lets you explore satellite constellations.
SaVi can be run either as a stand-alone program, or as an “external module” for the Geomview program. The latter mode enables three-dimensional visualization of the satellite constellations, but also requires Geomview.
This is free and open source software.
Key Features
- Constellations menu allows you to load in simulations of known satellite constellations, both existing and proposed.
- Coverage panel – a map projection of the Earth and visible coverage is shown.
- Fisheye window shows a view of the sky looking upwards from the ground, with the horizon around the outside of the circle.
- Can use Geomview or 3D rendering of Earth and satellites. Supports 3D texturemapping of the Earth sphere to Geomview, if OpenGL is supported.
- Can use gifsicle for saving animations of satellite coverage.
- Cross-platform support – runs under Linux, macOS, and Windows.
