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.

A simple command to convert calendar dates to julian dates. Quite useful in timing situations where you need elapsed time between dates. Also useful for astronomy applications.

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.

Satellite Prediction Server and Clients

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.

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

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

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/).

The Java Astrodynamics Toolkit is a library of components to help users create their own application programs to solve problems in astrodynamics, mission design, spacecraft navigation, guidance and control using Java or Matlab.

A self-sufficient java framework for numerical solution of ODEs (diff eqs) and visualization. Samples are aeronautics/astronautics/physics/rocketry themed. Focus on clean design, modularity, reusability and documentation. Educational project.

Native FITS viewer/IRAF image server for Mac OS X.

SPIDR (Space Physics Interactive Data Resource) is a distributed database and application server network, built to select, visualize and model historical space weather data. SPIDR is a web-application and a grid of data mining web-services.

Feature extraction toolkit based on a wavelet multiscale vision model. Includes 1D signal processing sample application for line identification and classification of astronomical spectra.

Simulation of star movements with great visualizations of flights through star fields.

Now maintained at github.com/spacepy/spacepy Space Science library for Python - contains superposed epoch classes, drift shell tracing, access to magnetic field models, streamline tracing, bootstrap confidence limits, time and coordinate conversions, etc.

StarMap 3D: the project aims to offer a fast and easy consultation of stellar systems

Portlets to submit VisIVO Server jobs to analyze and create customized views of 3D renderings from astrophysical datasets.

VisIVO Server is a new tool specifically designed for a grid environment. This tool offers a framework for exploration of large-scale scientific datasets, particularly related to cosmological simulations.

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 ...

chklinks is a non-threaded Perl link checker. It helps finding broken links on your website. It does not raises many simultaneously connections for its job, run out of the resources and crash your system in a moment.

GLNebula is a program designed for the real-time visualization of planetary nebulae models produced by photoionization codes. It uses camera-oriented quads and point sprites to achieve real-time speeds, also provides free camera movements.
