Giza Sattools
Current state: it works.
See above screenshot from port of skymap.
See above screenshot from port of satmap.
See above screenshot from port of satorbit.
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 giza-dev etc.
Giza
Here are two examples of how skymap should render, in this case using
pgplot (thx Pierros and Cees):
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:
More pgplot colors.
Giza sizing needs fixing...
SatNOGS TLE loads and renders.
There is an error that spams out to the console:
%giza - Warning - giza_set_character_height: Invalid character height, character height not set
The character heights are set to various values, typically 0.6, 0.8, and
1.0. Only 1.0 doesn't produce the error. But it renders much larger...
This has no errors, but looks bad. Overall need new font.
Satellite orbit lines rendering.
More, but not rendering so great...
Grid, but rendering with dots, not lines...
Rest of grid (blue background during day).
Equatorial. Hit o when skymap first launches, then it will re-render
with a faint equatorial "dot line circle"...
Remove broken constellations looks better for now.
fix orbit lines, maybe correct. need to confirm against main version.
Revert back to original size. Full size now, see top of page.
Works
Testing/dev in Debian Bookworm (testing), with giza version 1.3.2.
Out of box, this works:
- Sun.
- Moon.
- Besides the display, all the other functionality works.
Can load a
satnogs.tle, get satellite info, schedule, etc.
Fixed
skymap, satmap, and satorbit have been ported.
- Stars.
- Text header with date, observer, lat/lon/elevation.
- Footer with R, D etc.
- Rectangle.
- Apex renders.
- Grid renders.
- Satellites' colors.
- Orbit lines.
- FOV (but disabled by default upstream).
- Lines are dots not lines.
- Small window size with giza in
skymapandsatmap. - Small window size with giza in
satorbit. - Font. OK now.
TODO
- Constellations only partially rendered in
skymap. Disabled. - Check license status of
sgdp4.candsgdp4h.h. - Slow.

Color
Colors 1-15 are used in the color index, documented here:
Colors are off because giza uses it's own palette by default.
What is needed is to add giza.h and set this to use pgplot colors:
giza_set_colour_palette(1);
Satorbit
satorbit has the same issues as skymap.
Here is what it looks like out-of-the-box with Giza:
Fixes to colors, and "lines" drawn as dots:
Latest at top of page.
Satmap
satmap has the same issues as skymap.
Here is what it looks like out-of-the-box with Giza:
Fixes for color, screensize, and dots for lines... Latest fix at top.
