Roadmap for sattools development
This document describes planned changes to the sattools repository.
Background
The sattools began as a set of tools to help with tracking satellites using video and photographic cameras. The choice of C was one of familiarity with the code. Where possible, available libraries such as wcslib, gsl, qfits and pgplot were used. Some of these libraries are hard to build, raising the threshold for using sattools.
With python becoming more and more popular, it makes sense to port some of the sattools functionality over to python, and use powerful libraries such as numpy, scipy, astropy, matplotlib and opencv for the core calculations of these tools. Porting the tools to another language has the added bonus that it is easier to solve mistakes made in designing the C code and improve functionality.
Planned changes
The applications of the sattools repository can be divided into three categories;
- general purpose tools
- tools for video observing
- tools for photographic observing
Tools for radio observing have already been developed in their own repository strf: https://github.com/cbassa/strf. Porting tools for video observing is currently underway in the stvid repository: https://github.com/cbassa/stvid. The tools for photographic observing will live under a future repository, likely to be called stphot. An experimental project to use all-sky cameras for satellite observing is being developed in the asm repository: https://github.com/cbassa/asm (this could be renamed to stasm or stas; better suggestions are welcome).
