sattools

This is a fork of cbassa's sattools to try to get it to work with free software giza instead of proprietary and unmaintained pgplot.

Install

In Debian: libgiza0 etc.

Giza

This is a sample how skymap should render, in this case using pgplot (thx pierros):

This is how skymap renders "out-of-the-box" using giza as a drop-in replacement for pgplot:

Stars fix:

Text fix:

Rectangle fix, and grey:

Works

• Sun.
• Moon.

Fixed

• Stars.
• Text header with date, observer, lat/lon/elevation.
• Footer with R, D etc.
• Rectangle.
• Apex ?

TODO

• Satellites' colors.
• Orbit lines.
• Grid.
• Constellations only partially rendered.
• Small window size with giza.

Color Guesses

Colors 1-15 are used in the color index, documented here:

• https://sites.astro.caltech.edu/~tjp/pgplot/fig51.html

1   Black
2   Orange
3   Forest green
4   Blue
5   Dark gray
6   Purple
