This is the first half of a two-part blog post that is motivated-by and mostly "about" two software ecosystems I've been poking around at recently. The first (and subject of this post) is I'll roughly call "interactive scientific Python", which includes primarily SciPy/SymPy/NumPy, IPython, and Sage; the second (subject of next post) is a new interactive scientific language Julia, which has a lot of complicated and subtle relationships with the former. If you hate Python, skip this post because it is really just background for why I care about the fate of a few Python packages.

Gpredict is a real-time satellite tracking and orbit prediction application. It can track an unlimited number of satellites and display their position and other data in lists, tables, maps, and polar plots (radar view). Gpredict can also predict the time of future passes for a satellite, and provide you with detailed information about each pass.

A description how to use the MinGW-w64 tools in Cygwin.

The Amsterdam Compiler Kit is a cross-platform compiler and toolchain suite that is small, portable, extremely fast, and extremely flexible. It targets a number of low-end machines including the Z80, 8086 and 80386, but there are many other code generators available (including the pdp-11). It supports several languages, including ANSI C, Pascal and Modula-2, and contains integrated runtime libraries including a libc. While it used to be a commercial product, it has been made open source under a BSD license.

OREKIT is a free low level space dynamics library written in Java. It provides basic elements (orbits, dates, attitude, frames, ...) and various algorithms to handle them (conversions, analytical and numerical propagation, pointing, ...).
It the FAQ it is mentioned that the Two Line Element (TLE) package is well validated, even some errors in the original Fortran code from NORAD were found.
