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.

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

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 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.

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.

SITools2 is a new CNES generic tool performed by a joint effort between CNES and scientific laboratories. The aim of SITools is to provide a self-manageable data access layer deployed on already existing scientific laboratory databases.

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.

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

ProStack - a platform for image processing and analysis. It implements various image processing methods as separate modules, that can be joined in a complex image processing scenario by use of a graphical user interface. RPMs are available at https://build.opensuse.org/project/repositories/home:mackoel:compbio

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.

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

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.

CRUSH is a pioneering reduction and imaging suite for many astronomical cameras operating at far-infrared, submillimeter and millimeter wavelengths, such as SHARC-2, SCUBA-2, LABOCA, GISMO, or SOFIA/HAWC+ (to name a few).

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.

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.

Iridium flares prediction application

Parallel Spectral Deconvolution is a multithreaded ImageJ plugin for spectral 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.

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.

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.

SPIDR (Space Physics Interactive Data Resource) is a distributed database and application server network, built to select, visualize and model historical space weather data. SPIDR is a web-application and a grid of data mining web-services.
