The PDL module gives standard perl the ability to COMPACTLY store and SPEEDILY manipulate the large N-dimensional data sets that are the bread and butter of scientific computing.

SaVi - simulate Starlink, Iridium, Globalstar, O3b, GPS, Galileo and other satellite constellations, modify them, or design your own. Requires Tcl/Tk and Unix libraries; 3D viewing option requires Geomview running on X Window.

Yet another astrology software. Focused on Primary Directions. Based on Swiss Ephemeris. Still has a lot of things in queue to implement.

The Solar Model is real time modeling of solar system. It allows user to navigate in space, to control time counting (speed-up time flow) and estimate movement of space bodies, bind camera to space objects (for example, from Moon on Earth in real time).

This library is a Fortran 95 gnuplot interface for some Unix like OS'es. This provides some routines that enables direct access of a child gnuplot session from a Fortran 95 program. You will need a copy of fortranposix to make this work.

PMViewer is a Visualization tool for Astrophysical N-Body and Hydro Simulations. GADGET-2 data support.With/Without periodical boundary conditions.Snapshot of scene in PPM and GIF formats.Flying in 3D space. Active/Passive Stereo 3D support.

The primary objective of the project is the development of a Second Life based application, in which astrophysics phenomena involving the simulation of stars kinematics can be visualized. Developed by NII, Japan.

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.

The AOFlagger is a tool that can find and remove radio-frequency interference (RFI) in radio astronomical observations. The code has been highly optimized for speed and accuracy. It is used by default for the LOFAR radio telescope and thus is in productional stage. The software can run in a fully automated way, but a graphical interface is provided to analyse results and tweak the strategy. The preferred input file format is the Casa Measurement Set (MS) format. I believe that the AOFlagger is the best available flagger, both in terms of accuracy and speed. It has been succesfully used on several interferometric telescopes, including LOFAR, WSRT, VLA, GMRT, ATCA and MWA, and the single-dish telescopes Parkes and Arecibo 305m. Besides the flagger, the software consists of tools to efficiently visualize data in different ways, such as plotting time-frequency diagrams and power spectra. It provides the programs rficonsole, rfigui, aoqplot, aoquality and more.

AQUYNZA is a set of C++ libraries, sample programs and doc's for the modelling, visualization and persistence of 3D environments. Its modular and highly portable. Its primary objective is helping to learn (and teach) computer graphics. (code in SPANISH)!

Corikon is a simple software to visualise the correlation matrix of a set of data, using the iconography of correlations.The first step of the project has been reached: rendering the distribution of data according to the user wills.

Calculates the shape of a telescope mirror from a sequence of Foucault test images. Java-based GUI simplifies entering and organizing measurement data. Logging and comparison functions enable quantification of the effects of various figuring strokes.

Gnorbits is an open source 3-D orbit program. It supports multiple bodies of varying masses and initial velocities, using a GTK interface.

The Gerbil project moved to http://www.gerbilvis.org Please visit us there for up-to-date information and current software releases!

Global Village is a UI for xplanet on the Gnome desktop

Experimental OpenGl night sky rendering by making full use of modern PCs hardware. Writing another planetarium is crazy? It's Glunatic!

GravitySim is an application written in C# using Microsofts Windows.Forms for the GUI. It allows the user to place point masses on a coordinate map, and given velocity, calculates the orbits of the masses, representing it graphically.

GyVe (GalaxY ViEwer) is a visualization program for understanding the distribution of galaxies and clusters of galaxies.

It is a gnuplot library that gathers a set of functions to deal with problems of celestial mechanics. It allows one to easily accomplish tasks such as: - Converting orbital elements into Cartesian coordinates and vice-versa - Evaluate orbital position as function of the flight time and vice-versa - Plotting keplerian orbits easily

A high performance visualization tool for stars and particles able to run on Beowulfs. Rendering step is implemented separately and optimized for SSE, compatible with OpenGL. Navigation mechanism with quaternions. Ten color maps, sobel contour detect

Analysis software for Nbody/SPH or SPH simulations (e.g. performed with Gadget II). See http://sourceforge.net/apps/wordpress/hyplot/about and http://sourceforge.net/apps/trac/hyplot/wiki for more information.

JSatTrak is a Satellite tracking program written in Java. It allows you to predict the position of any satellite in real time or in the past or future. It uses advanced SGP4/SDP4 algorithms developed by NASA/NORAD to propagate the satellite orbits.

Jaude is "Java pour les Astronomes Utilisateurs de Detecteurs Electroniques". Jaude is Eclipse RCP and plugin based. So it will provide an Eclipse interface for JSky library (http://archive.eso.org/JSky/).
