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.

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.

As of August 2018 Spheral++ has moved to Github -- please see the current repository at https://github.com/jmikeowen/spheral We are leaving a frozen version here on SourceForge for historical reasons. Spheral++ provides a steerable parallel environment for performing coupled hydrodynamical & gravitational numerical simulations. Hydrodynamics and gravity are modelled using particle based methods (SPH and N-Body).

This program will enable you to find every solar eclipse in between about 2500 BC to 3500 AD. The central line can be displayed graphically and saved as a JPEG or PNG image file or as a PDF document.

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.

Parallel Spectral Deconvolution is a multithreaded ImageJ plugin for spectral image deblurring.

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

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.

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

Nowadays the idea of a music of the spheres, or a cosmic music that descends from the planets seems more like poetic philosophy than anything scientific. However, when the scientist Kepler discovered special principles about planetary motion, he also reconsidered the music. Apparently his observance of a harmonic law of planetary motion was reason for him to propose a computable system of pitch and harmony deriving from angular velocity. The purpose of the programming project is as a tool to examine his system. With Java 2, it provides an open-source solution for listening to harmonies so generated by planetary motion. This program can run on any computer provided with a Java Virtual Machine (Rev 1.5 or greater). JAVA 2, system independent. Purpose:to encourage research in harmony in astronomy, math and music. Obstacles:math, DSP/synthesis, networks, astronomy. Features:audio, database, graphics Technologies: Telnet, .WAV audio, oggvorbis, other audio

libTheSky is a Fortran library to compute positions of celestial bodies (Moon, planets, stars) and events (conjunctions, eclipses). It forms the core of the software that produces the Dutch popular-astronomy website http://hemel.waarnemen.com

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.

PHOEBE (Physics Of Eclipsing Binaries): scientific code for full-fledged modeling and analysis of eclipsing binary stars, build on basis of the WD code. It is actively being developed, its official homepage is at: http://phoebe-project.org

Python & NOVAS. Use Python to calculate the position of Sun, Moon, Planets and Stars with unprecedented precision. PyNOVAS can be used by (Amateur) Astronomers, Sailors and other people interested in Celestial Navigation, Astronomy and Astrometry.

A collection of Java ports of open source terrain and solar system generation packages. Code has been extensively refactored, extended and documented. GPL License with exception for required libraries.

AstronomicalAlgorithms is a FREE portable ANSI C implementation of some of the algorithms published in Astronomical Algorithms by Jean Meeus (2nd edition, December 1998, Willmann-Bell ISBN 0943396638)

Warning: I found an error if the DR position is on the southern hemisphere. The PUB249 pdf files did not show this error and are correct (as far as I checked). All Revisions 8+ and the Windows release have been fixed. This Python TK application calculates a good set of stars for a 3 star fix, makes all calculations similar to the FAAs Celestial Computation Sheet (see FAA doc FAA-H-8083-18). Also, you can create a PDF file that generates Pub 249 Vol 1 for any epoch you specify. The PUB249 as PDF is found under "Files". I wrote this for my aircraft bubble octant :-) It is mainly useful for air navigation as it assumes a bubble sextant but may be used for normal sextants as well. Requires Ephem and ReportLab (optional for PDF output) Not to be used for real-world navigation!

Ham's Actor is a software for radio hams. Is a bundle of many functions and tools, so you just have to have one software. Functions: Log Book, GrayLine, satellite tracing, contesting, maps, callbook, and so on...
