Open Source ChromeOS Astronomy Software

PreviSat is a satellite tracking software for observing purposes. Very easy to use, it shows positions of artificial satellites in real-time or manual mode. PreviSat is able to make predictions of their passes, predictions of MetOp and COSMO-SkyMed flares, transits of all satellites, predictions of Starlink satellites passes and several other calculations.

The PDL module gives standard perl the ability to COMPACTLY store and SPEEDILY manipulate the large N-dimensional data sets that are the bread and butter of scientific computing.

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.

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.

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

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.

Java software that predicts transits of any satellite, including the International Space Station, across the moon and sun, and close encounters with Mercury thru Saturn.

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.

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.

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

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.

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)

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.

extra astronomical / calendar / epoch features that mathematica does not have. has many new functions. supports multiple calendars (julian, gregorian, synodic, anomalistic). supports JDN conveniently, shows moon phase est. NEW: supports day number from 0 of any calendar conversion all-way between supported calendars supports multiple epochs and epoch generation. convert between some epochs without calendar support, ie, J2000.0, JDN, to some effect can create/import epochs and use TAI clock << Months`Months` {PrettyDate[], PrettyDate[calendarChange2[Date[], gregorian, julian], julian], MoonPhase[]} {"Sunday, July 13 2014. 2:37:04 p.m. -4 GMT", "Saturday, Iunius 30 2014. 2:37:04 p.m. -4 GMT", "Full Moon"} timeDeduce, a minor extra: deduce and show other times / angles, using time eqn. input: GMT,lon,tz,arieslon output: input + SHA,Ra,LHA ; in dn,tm or ang (for historic reasons files are also in https://sourceforge.net/projects/periodictablemm/)

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

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.

JAVA project represents the realization of modern astronomical algorithms related to the orbital movement of planets, satellites and small bodies in the solar system by solving Kepler's equation and additional astronomical and mathematical libraries

Java classes to access FITS files. Library is based on modified nom.tam.fits classes.

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

SolarBeam is a desktop application for drawing solar diagrams. You supply the geographical position, it draws a diagram showing the Sun's trajectory over your location at various times of the year. It also shows the times of sunrise and sunset.

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.

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.

This project contain application to extract images from arch.H format used by Asteroid Data Hunter, and also compiled releases of updated versions of Asteroid Data Hunter itself.
