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.

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.

PlanetPack is a software tool developed to facilitate the radial-velocity time-series analysis for the goal of exoplanets detection, characterization, and basic dynamical simulations. The description of the main theoretic concepts, statistical methods and algorithms that PlanetPack implements, is given in the following refereed papers: R.V. Baluev 2013, Astronomy & Computing, V. 2, P. 18 (initial release); R.V. Baluev 2018, Astronomy & Computing, V. 25, P. 221 (update 3.0). The technical manual explaining the details of the practical use is available in the download archive here (see the /doc/ subfolder).

ACRASH is an open implementation of the CRASH Monte-Carlo continuum radiative transfer scheme presented in Ciardi et al. 2001 and Maselli et al. 2003. This code solves the radiative transfer equation for any geometry in 3D using a Monte-Carlo scheme.

Ciclope Planetarium is a web-based planetarium that provides a simulation of the sky from any location at any time and date. Developed using Google Maps API & AJAX. Available in PHP & J2EE. Integrated in the Ciclope Stars project (www.ciclope.info/stars)

GGOS is a Graphical Simulator of the gravity interaction written in C. It provides a real-time tracking of the orbit and the user can interact with the universe with a lot of function. There is 2 different version:1(fast)with X11 2(slow)written with GLUT

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.

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.

Optical design application geared to telescopes and other optical systems. Features include layout design, optimization, standard expected output, ability to import ZMX and LNS files

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

jSGP is a Java implementation of the five SGP/SDP propagators described in NORAD's Spacetrack Report No. 3.

Pysolar is a Python library for calculating the position of the sun relative to the earth as a function of latitude, longitude, and time. There is also code included for other problems related to the development of photovoltaic systems. Still in alpha.

QuantimSim is a physics simulation engine. Some aspects of astrophysics, electromagnetism, relativity, thermodynamics, statistical mechanics and quantum mechanics will be included in the simulation library.

SENSITIZER is an ESO software toolset written in Matlab and Mathematica aiming at automating some Structural/Thermal/Optical Performance (STOP) sensitivity analyses with Zemax OpticStudio (ZOS). The core code of SENSITIZER runs in MATLAB and drives ZOS in the background through the ZOS-API interface, based on .NET. The output is saved in the MATLAB file format and can be post-processed using MATLAB and/or Mathematica routines. The optical system to analyze is defined in a normal Zemax lens file. The core data structure of SENSITIZER is an optical group, which can be any optical surface in the lens file or a set of subsequent surfaces. These groups will be perturbed by varying their positions relative to the rest of the system (rigid-body-motions) and/or by adding Zernike shape deformations on their front surface. After a certain perturbation is applied, ZOS runs (sequential) raytracing to compute the optical performance such as centroid displacement or wavefront error.

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).

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

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.

Libpsht is a collection of algorithms for efficient conversion between maps on the sphere and their spherical harmonic coefficients. It supports a wide range of pixelisations (including HEALPix, GLESP, and ECP). Development for this libary has stopped; its successor is libsharp (http://sourceforge.net/projects/libsharp).
