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.

CosmicOS is a framework for creating stand-alone messages suitable for sending to ourselves in the distant future, or to use in SETI research. It is inspired by Hans Freudenthal's language, Lincos, and Carl Sagan's book, Contact.

The aim of this project is to produce high-res/quality printable star maps according to your latitude. This projected was founded at the Deutsche SchülerAkademie Steinmühle 2004. It's a cooperation of the astronomy and cg courses.

DSPSR is a high-performance, object-oriented, digital signal processing library for radio pulsar astronomy. It implements an extensive range of algorithms and features, and can read data from most observatories, instruments, and file formats.

A set of cross-platform tools for connecting via TCP/IP to the VOEvent transient astronomy alert network. Tools include a receiver/broker, a sender/publishing tool, and a VOEvent message checker. Runs on Linux, Mac OS X and Microsoft Windows.

A client program compatible with the INDI standard (see http://indi.sourceforge.net) for remote telescope and device control. It works under Windows as well as Linux. It is writen in Python and uses the GTK in order to display the GUI.

Note: This project is no longer maintained. A newer version of the program is at https://code.google.com/p/digest2/. Statistical ranging for short arc moving object astrometry. Accepts atstrometry in MPC 80 charcater observation format, rates objects on likelyhood that they are yet-unknown near Earth objects.

Generate star maps for anywhere at anytime. Choose from a database of thousands of deep sky objects, including all Messier, Caldwell, and NGC objects. Also allows recording of notes on viewed objects, and configuration of user-generated observation lists.

Java library to calculate heliocentric and geocentric planetary positions. Two types of calculations are supported: a 'fast' version which has an accuracy of about 1 arc second and a 'full' version that implements the full VSOP87 theory.

Program to calculate Easter date for any year. It can also display palm Sunday, Ash Wedenesday, Lent and other dates. In the future, it will be a complete holiday calendar.

Der Elektro-L Gif-Maker erstellt aus Bildern, die von der russischen Raumfahrtagentur zur Verfügung gestellt werden, GIF-Animationen der Erde der letzten 24 Stunden. Dabei werden die 10 Kanäle berücksichtigt sowie eine Gesamtanimation in RGB berechnet. Dank geht an websquid für die Idee. Reimplementiert in C und nach Github umgezogen: https://github.com/simonpl/elektrol-gif-maker Logo: NTS-OMZ

ExCon can create images with a very wide field of view (more than billion pixels). It implements novel gridding and image weighting algorithms. It is well suited to make ultra deep radio interferometric images, minimizing aliasing artefacts and PSF variation. NVIDIA GPU acceleration is available. JAVA/SCALA support available.

This is a parallelized algorithm performing a decomposition of the time-series data into a number of sinusoidal components, disentangling them from the white Gaussian noise. The algorithm analyses all suspicious frequencies, including the ones that look like an alias at a glance, but may become preferable later. After selection of the initial frequency candidates, the algorithm passes through all their possible combinations and estimates their multi-frequency statistical significance. In the end, it prints out the set of largest frequency tuples that were still found significant. The GPU computing is implemented through CUDA and brings a significant performance increase. It is still possible to run FreDec solely on CPU, if no suitable GPU device is available in the system. See the details of the underlying theory in Baluev 2013, MNRAS, V. 436, P. 807 The description of the algorithm itself can be found in arXiv:1309.0100. Please go to the project forum to report any bugs.

Freydis is a fork of the Eirik data exploration application. "Eirik is a tool for exploring large data sets, by using statistical analyses and multiple linked visualizations for data reduction." Freydis will continue Eirik's development.

GBTIDL provides offline data reduction for spectral line data from the GBT, a single dish radio telescope. Although the GBTIDL code is open source, running it requires you to have your own IDL license and base package.

GIRAFFE Base Line Data Reduction Software is a set of python scripts and modules and a C library to reduce FITS images produced by the Very Large Telescope (VLT) FLAMES instrument.

GLORIA stands for "GLObal Robotic-telescopes Intelligent Array". GLORIA will be the first free and open- access network of robotic telescopes of the world. It will be a Web 2.0 environment where users can do research in astronomy by observing with robotic telescopes, and/or analyzing data that other users have acquired with GLORIA, or from other free access databases, like the European Virtual Observatory (http://www.euro-vo.org).

displays the current phase of the Moon as an applet for the gnome panel. Clicking on the applet displays sundry data pertaining to the moon including various clock functions. The user can select between a real image as well as a cartoon image of the

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

The GPU-BH tree solver is a FLASH4 module to calculate the gravitational potential using a CUDA device.

GRad is a standalone solar radiation model, programmed in Java. It is capable of the calculation of potential (clear sky) and actual (real sky) irradiance and total irradiation for single and multiple geographical locations. Note that, while fully functional, this application is currently not developed any further.
