PreviSat is a satellite tracking software for observing purposes. Very easy to use, it shows positions of artificial satellites in real-time or manual mode. PreviSat is able to make predictions of their passes, predictions of MetOp and COSMO-SkyMed flares, transits of all satellites, predictions of Starlink satellites passes and several other calculations.

As of 2020, this project has moved. See https://mesastar.org. Release versions can be found on Zenodo at https://doi.org/10.5281/zenodo.2602941. The code is now hosted on GitHub at https://github.com/MESAHub/mesa. You can find the documentation at https://docs.mesastar.org/.

PROPER is a library of routines for the propagation of wavefronts through an optical system using Fourier-based methods. It was developed at the Jet Propulsion Laboratory for modeling stellar coronagraphs, but it can be applied to other optical systems were diffraction propagation is of concern. It is currently available for IDL (Interactive Data Language), Matlab and Python (3.x). It includes routines for generating complex apertures and obscurations and aberrations (Zernike & PSD-defined). It includes a model of a deformable mirror for wavefront control. The routines perform near and far field propagation with automatic selection of propagators. The latest version is v3.31 released on 12 Nov 2024. Please report any bugs using the Tickets tab.

The Ground Station Software Suite projects aims at providing free, useful software tools for ham radio operators. Currently, this projects hosts the Grig communication radio control. The source repository has been moved over to github.

Aciqra is a virtual planetarium and sky mapping program which tracks celestial bodies including planets, deep sky objects and stars to an accuracy of a fraction of a degree for thousands of years into both the future and the past. It includes the 2.5 million stars of the Tycho-2 catalog supplemented by data of 120,000 stars from the Hipparcos catalog, 13,000 deep space objects from the NGC and IC catalogs and a large number of asteroids and comets from the Minor Planet Center. The program is platform-independent and can be made to work on most modern computers that support OpenGL.

QuickFlash is a C++-based analysis library for data files generated by the Flash hydrodynamics code. It provides high-performance access to large datasets in low memory situations and other restrictive environments.

X-Bc (formerly: xbc) is a graphical user interface to the command line calculator bc. All Inputs and Outputs stays visible for editing and comparing. Functionality: trigonometry, number-theory, exponential funcs, scientific constants, primenumbers ...

Plot package for GALPROP https://sourceforge.net/projects/galprop Plots models and data for cosmic-ray spectra, secondary/primary ratios, gamma rays, synchrotron. Includes gamma-ray source population synthesis and corresponding plots. For gamma rays, convolves models with the Fermi-LAT response. This release is to assess interest. It requires many input data files (not included) which will be made available as required. With the data provided cosmic-ray spectra and ratios and source population synthesis will work. Uses CERN root package. See README for details. Plots produced with GALPLOT can be seen in http://arxiv.org/abs/1101.1381 http://adsabs.harvard.edu/abs/2011A%26A...534A..54S http://adsabs.harvard.edu/abs/2011ApJ...739...29B and http://arxiv.org/abs/1309.2947, published version: http://mnras.oxfordjournals.org/content/early/2013/10/03/mnras.stt1718.abstract . Uses the cosmic-ray database https://sourceforge.net/projects/cosmicraydataba
