gSky Digest is a system tray desktop application that presents astronomy events calculated for your home location. Currently it comes with detailed information about the Sun, the Moon and 7 planets. See Project Web Site for more details.
Model of the Solar System
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 is an interactive graphical 3D simulation of the orbital mechanics of the planetary motion in the solar system and galaxy. It specifically concentrates on the phenomenon related to the sun, moon and the earth.
MobileStarChart is a MIDP1.0/2.0 midlet for Java-enabled mobile/cell phones or handheld device. It simulates whole sky at any point on earth with constellations, stars up to 6 mag, solar systems and some other celestial objects.
The JSky package contains java classes for displaying astronomical images, searching astronomical catalogs and plotting catalog symbols on images. The jskycat application is also included and makes use of most of the features.
A scientific plotting library for C/Fortran built on cairo
A 2D scientific plotting library built on cairo. Provides uniform output to pdf, ps, png and X-Windows. Written in C with no dependencies (other than cairo) as a direct replacement for PGPLOT.
Telescope mirror surface error analysis from interferograms. Includes 3D solid model, color Contour plot, quality metrics, and surface profile.
EXTREMA is an interactive program with publication quality graphics and mathematical analysis capabilities. EXTREMA can be GUI and/or command driven. The command language includes conditional branching, looping and subroutine calling constructs.
Siril is an astronomical image processing software for Linux.
Siril is an astronomical image processing software for Linux. Dev here is stopped: as of 2013/02, Siril development has moved and is regaining activity here https://free-astro.org/index.php?title=Siril
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.
Open source observatory control software
RTS2 is project to create an open source environment for control of a fully autonomous observatory. It is running about dozen fully autonomous observatories. Its modular design allow easily addition of new devices (to already huge supported HW list).
Parallel Spectral Deconvolution is a multithreaded ImageJ plugin for spectral image deblurring.
Linux modified webcam capture software for astronomy. This project is a fork from the great Qastrocam, written by F. Sicard (http://qastrocam.sourceforge.net/). It adds some features I wrote for myself.
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
Dark Master allows astrophotographers to quickly match dark frames
Dark Master allows astrophotographers to quickly match dark frames to light frames based on temperature. The inputs to Dark Master are the directories to the light images and dark images. The output is a DeepSkyStacker file list.
ASCOM driver for the LittleFoot Elegance Photo (LFEP) telescope controller. Firmware 6.x is fully supported - firmware 5.x is partially supported (all LFEP features are available but configuration is only possible by handbox). Contains drivers for telescope, focuser, camera, filter wheel, roof controller and dew heater which shares a single connection to the controller.
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...
Yet another astrology software. Focused on Primary Directions. Based on Swiss Ephemeris. Still has a lot of things in queue to implement.
Univerx, a Solar System simulator in OpenGL 3D to show planet's translation and rotation. Includes phisical simulation of orbital movement, textured and lighted planet surfaces and customizable interactive view of the model.
Pulsar software for forming timing residuals. Developed mainly by George Hobbs and Russell Edwards at the ATNF.
Astrosoft is a free indian astrology software program for astrologers and astrological students. Its a Java Swing based GUI Application. It provides Birth chart of individual with details of Lagna, Rasi, Nakshata, Thithi, Paksha and many more features.
Java software that predicts transits of the International Space Station across the moon and sun, and close encounters with Mercury thru Saturn.
This project contains two packages. An Orbital Mechanics Study developing the physics equations related with satellite tracking and a libtool C++ library to encapsulate the satellite tracking calculations (gsat).
Open Source Astronomy Tools
Open source tool to assist with study of Astronomy, Astrophysics and Cosmology. To include usefull data and calculation of common equations used in the basic study of these subjects. Later versions may interface to other existing Astronomy software t
