libnova is a general purpose, double precision, celestial mechanics, astrometry and astrodynamics library.

Java based astronomical logging software which stores it's data in a free and open XML based format (OpenAstronomyLog). Discontinued project: Please check out the fork: https://github.com/capape/observation-manager for an updated version

Modern, nice software for astrologers. Contains different views of horoscope: classical chart, planets view and plain text. Provides detail information about each element of horoscope. Uses 9 house systems, over 40 aspects for horoscope calculation, tropical and sidereal sign and much more.

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.

The Mars Rover Simulator project is based on the evolutionary robotics paradigm where an artificial agent acquires its skills through the process of artificial evolution. This simulator can be useful to evolve neural network controllers for the rover

VStar is a multi-platform, easy-to-use variable star observation visualisation and analysis tool. Data can be read from a file or the AAVSO database, light curves and phase plots created, period analysis performed, and filters applied. Plugins can be developed, e.g. to make additional observation sources available.

Parallel Iterative Deconvolution is a multithreaded ImageJ plugin for iterative image deblurring.

SIGPROC - a collection of signal processing programs developed for pulsar data reduction has been developed and maintained since 1999. The package is used to search for and visualize the presence of pulsed signals in noisy radio astronomy data.

MoonPlanner is a Java calendar that allow to view moon's phases, moon's signs (constellations in which the moon is), and show the part of the plant corresponding to each sign (flower, fruit, leaf or root). For every calendar's day the user can attach notes (that are stored in a persistent database). At the startup the program will remind you if there will be notes for current day. Timezones and localizations (En, IT) are supported by the application. This calendar is usable between 1900 and 2020. This tool can be useful to plan gardening tasks or to view some astrology informations. References and requirements: - JRE/JDK version 1.5 or later must be installed on host computer. - UI are made using SWT by Eclipse (see http://www.eclipse.org/swt/). - The software uses AstroLib library version 1.1.5 provided by Mark Huss to calculate Moon's phases (http://mhuss.com/AstroLib.html). - The software uses Apache Derby 10.9.1.0 (http://db.apache.org/derby/) as embedded database.

PSRCHIVE is an application suite and development library for use in the storage and analysis of pulsar astronomical data. It includes an extensive range of algorithms and tools commonly used in a wide variety of experiments.

Project to calculate and distribute the general relativistic corrections to clock rates for the surfaces of various solar system bodies. These corrections are also known as time ephemerides.

Numerology diagram creator with aim to ease making numerology interpretations.

OpenAstrology is Java based Object-orientated implementation of Astrology. OpenAstrology will provide a platfrom to plug-in in the knowledge of Astrology and the derived solution will be the best real time Astrology solution

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.

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.

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.

he JAVA library is designed to read JPL DE/LE ephemerides (DE200, DE405, DE406, DE421, DE422, DE430, DE431, DE440 and DE441) and to calculated the position and velocity of the Sun, Moon, eight major planets and Pluto, also the earth nutations and the lunar librations if they are part of the ephemeris.

BoPlanets is a virtual planetarium showing the planets relatively to any observing planet. The planets can be viewed in ecliptical-, equatorial- or horizontal view. The times of rise, transit and set of a planet can be determined. Click on the link below to the web site of BoPlanets to see the help file of BoPlanets.

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.
